Wonderful Season

Over the past week a number of people, some who I know and others who I do not, have come up to me various places around town to comment on the Stonewall Brigade Band season. Comments were particularly favorable for our "Best of the Season" concert. One regular member of our audience came up to me at Jazz in the Park's last concert and commented that the band's "connection" to the audience was particularly good throughout the season. Other comments were that the band "sounded great" or was "wonderful." Congratulations and thanks to all the members who so faithfully came to perform each week and did a really great job.

Rehearsals start the last Monday in September with an emphasis for that rehearsal on our Oktoberfest performance the following Saturday. Starting with the first rehearsal in October (Mondays, 8-9:30 at the band room) we will be learning new pieces for next Summer's series and other performances. This is a change to our regular plan. We will be using our Spring rehearsals to polish those pieces and add them to those that are already in our repertoire.

Concert Season Off To Great Start

Last night we started the 2010 concert season. This is my 50th year as a member of the band and my 35th year as director.

The band numbered about 75 players and was quite well balanced.

Balance within sections and between sections was excellent. Dynamic control was also excellent, and melodic lines could be clearly heard. Intonation was also excellent.

The concert lasted an hour and fifteen minutes, and the audience numbered about 270.

This very musical performance was a joy to conduct.

Tonguing on brass and woodwinds

In rehearsals recently we have been working on speed of tonguing, particularly in marches.

Here are a few hints:

For everyone; Anchor your tongue on your side teeth. Ideally the teeth should be apart enough that the tongue can slip into the space between the upper and lower molars-- just behind the "pointy" canine teeth. This keeps the movement limited to the far front and mid-back of the tongue. It also keeps air from puffing the cheeks and avoids overly-tight face muscles. This helps your tone.

For clarinet and saxophone: There are two methods of tonguing-- "tip to tip" and "anchored tip." Tip to tip means the tip of your tongue touches the reed with a "d" or "t" syllable. Anchored tip means the tip of your tongue stays touching your lower teeth, below where your lip curls over them, and the reed contacts your tongue farther back from the tip, like you were saying the "ch" sound--- "chu". The way to tell which method to use is simple. Stand in front of a mirror and put your finger right in the middle of the "ball" of your chin. Then try to touch your finger with your tongue. If you can't touch your finger with your tongue, use tip to tip tonguing. If you can touch your finger, use anchored tip.

For flutes and brasses: the tip of your tongue touches the front side of the ridge that goes across the roof of your mouth just behind your front teeth. At no time should your tongue touch your upper teeth.

Double touguing for sixteenth notes and faster:

Note-- for this to work the air must move quicker than normal.

Flutes... the syllables are du and gah, so four sixteenth notes would be du ga du ga. Practice until you can say this smoothly and then try playing it on one pitch over and over.

Trumpets --- ta ka is the usual syllable combination for double tonguing on trumpet. Du gah can be use for a less percussive attack.

Trombones/Horns/Baritones/Tubas -- du gah is probably better for you.

Single reeds-- you can "fake" double tonguing using anchored tip and the syllables chu kah. Practice this without your horn until you can do it. It takes more air than normal to make it work.

Flutter tonging. The trick is to move the "side anchor point" up onto the upper teeth and move the touching point just behind the ridge in the roof of the mouth. Then put a lot of air through very fast. Try this without your horn until you can do it, then try it on the horn.

Upcoming concerts

The Stonewall Brigade Band will play a concert at the Bushong Farm area of the New Market Battlefield State Park at Noon on Saturday May 15, 2010. The concert will feature Civil War music with Frank Sampson conducting.

The band will play for the 33rd consecutive year for Baccalaureate and Commencement for Mary Baldwin College on Sunday May 23. The prelude begins at 9:30 followed by the Academic Procession at 10. The event concludes around noon.

The band will play a concert of patriotic music on Memorial Day, Monday May 31 starting at 9:45 am at the Stonewall Brigade Bandstand in Gypsy Hill Park, Staunton VA. This is part of the VFW annual Memorial Day ceremonies.

The annual series of Concerts In The Park will begin on June 7. Concerts are every Monday in June, July, and August at the Stonewall Brigade Bandstand in Gypsy Hill Park. Concerts begin at 8 pm and are held rain or shine. Bring your lawn chair and enjoy an old fashioned band concert under the stars.

How important is a warm up?

Certainly we all agree that it is more fun to play in the band when the band sounds really good. One of the key elements in getting that "good sound" is a good warmup routine, both in individual practice and in the full band rehearsal.

You can find many good articles on the internet about warmup routines for your particular instrument. I have just two tips in today's posting:

For percussionists... work on making the sound of each hand be the same. You can practice this little exercise anywhere with just a pair of your favorite drum sticks:
L R L R L R L rest R L R L R L R rest (repeat ad infinitum, at all speeds, but start slowly) Have a friend or family member listen to you and try to tell which hand you started on. The objective is to make exactly the same sound with either hand.

For everyone else:
Play a scale... any scale. Do it slowly, and go over as much of your instrument's range as possible. Listen for the one note that has the very best tone... nice and full, resonant, and it seems to envelop you and fill the space around you. Play that note over and over 6-8 times, holding it a long time. Then try to get the same exact tone quality on the note 1/2 step higher. When you get that done, try 1/2 step lower. Over a period of weeks or months you can expand your "beautiful tone" range over the entire range of the instrument.

For a full band warmup we have two objectives which are related. We want to achieve agreement among all the players on pitch and on rhythm. Playing a scale in unison and in chords is good for matching pitches. Of course you have to listen to yourself, to your neighbors, and most importantly across the band to everyone else. Things like playing 4 notes on each scale tone, playing "oom-pahs" and playing scales with various rhythm patterns help clarify the feeling of pulse in the band and help us play rhythms exactly together. That very part of the warmup that you personally dislike, is probably the part of the warmup that can help you the most as you improve as a musician. Put your entire energy into the warmup and strive for perfect pitch and rhythm matching across the entire band.

A book for Summer reading

For those days when you have time on your hands, but it's a rainy day
and you can't go outside, and you have already practiced on your
instrument, there's a book you might want to buy and read. The book
is "Note Grouping" by James Morgan Thurmond. This classic is now
available in paperback. I lost my hardcopy book a number of years ago
and just ordered the new paperback version from Amazon.com. Thurmond
started his career as a French Horn player in the Philadelphia
Orchestra, was the main person in establishing the Armed Forces School
of Music at Little Creek (starting it as the Navy school of music),
and finished up as a college professor. Along the way, about 30 years
ago, he conducted regional bands in this area and judged my high
school band on several occasions (and gave us a superior rating, by
the way.) The book explains WHY you accent the pickup note. It will
greatly help you in playing with expression. Happy reading!

Concert Season 2009 is here!

Thirty-Four years in the park for me, 121 years for the band, and 154
years of continuous operation for the band. Wow!

Frank Sampson and Ray Hoaster continue as assistant directors, with
each taking a full concert and Frank conducting about a third of most
of the concerts.

This year's concert lineup features premiere performances of several
pieces written for the band by members and band friends. Ray Hoaster
wrote a nice arrangement of the Rodgers and Hart tune "Mountain
Greenery" to showcase the clarinet talents of Al Winters, our oldest
member, who at age 83 is still going strong. Bob Moody did
transcriptions of two pieces for the band. First there's the
Victorian church anthem "The Lord Is My Strength" by the british Caleb
Simper, and then there's one that is given as a Carl Broman tribute,
Healy Willan's Organ Chorale Prelude on the hymntune "Now God Be
Praised In Heaven Above." On the joint concert with the 29th Army
Band we will do the premiere performance of "Afghan Andy" by Randolph
Cabell, honoring Army Major Andrew Ashley upon his return from
Afghanistan.

Concerts are held regardless of weather in the Stonewall Brigade
Bandstand in Staunton's Gypsy Hill Park. Directions and concert
programs can be found on the band's web site www.stonewallbrigadeband.com
under the "concert series" tab.

Come and enjoy an old-fashioned band concert under the stars every
Monday evening at 8 in June, July, and August.

Concert Season is Here!

The Stonewall Brigade Band's Summer season starts this weekend with
two of our annual events.

Saturday we will be playing at the New Market Battlefield Park as a
part of the annual reenactment of The Battle Of New Market. The
concert is at noon in a tent just outside the Hall of Valor at the
park. There is an admission charge to the park (but of course band
members get in free.)

Sunday will be the 31st year that the band will play for the
Baccalaureate and Commencement at Mary Baldwin College in Staunton.
We play a 30-minute "prelude" concert at 9:30 am, then the
processional, a hymn, and after the conferring of degrees we play the
Mary Baldwin Hymn and the recessional. I arranged "God of Grace and
God of Glory" for this event 31 years ago, and our librarian, Cindy
Hosaflook, updated it by putting it in to Finale and undoing a
modulation to the last verse about 5 years ago. I also arranged the
MBC hymn which is sung to the tune of "Children of the Heavenly
Father" at the same time. Our processional is the typical "Pomp and
Circumstance" main melody, as arranged by James Ployhar, and our
recessional is Alfred Reed's arrangement of R. Vaughan Williams' "Sine
Nomine". The event is held on the terrace on the "uphill side" of the
library, and moves to Augusta Expo half an hour later in the event of
rain.

Our Brass Ensemble will be playing for two annual Memorial Day events
over Memorial Day weekend. All band events can be found on the
"schedule" link on the band web page.

The 120th annual season of Summer Concerts in the Park will begin on
June 2 and will continue every Monday at 8 pm at the Stonewall Brigade
Bandstand in beautiful Gypsy Hill Park in Staunton VA. Concerts are
held "rain or shine," and the programs are shown on our web site.  

This is Bob's 33rd year of conducting the Summer Concert Series.  It is the 120th-annual season of concerts in Gypsy Hill Park, going back to the year the park was established and the trees were planted.  This is the 154th continuous year of service for the band. 

We have added over 20 new members to the band since last Summer, and
expect this season to be one of the best ever. As always, band
members begin setup about 7 pm, with tune-up at 7:40 and downbeat at 8
pm. Concertgoers should bring lawn chairs or blankets, as there is
limited permanent seating at the bandstand. In addition there are now
several "pull in" parking spaces available on the "horseshoe" section
of the park drive so that handicapped persons can listen from their
cars. Come early for best parking.

Special Musical Event at UVA on March 29, 2008

When I was a student at the University of Virginia from 1958 through 1963 I practiced on the Ernest Skinner pipe organ in Old Cabell Hall.  This organ is the oldest surviving Ernest Skinner instrument in its original location and in its original condition.  Along with the Tannenberg organ, 200 years old, in Hebron Lutheran Church, Madison VA, The Cabell Hall Skinner is one of the musical treasures of the nation.  

The McIntire Department of Music is having a special Skinner Organ Centennial event on Saturday March 29, 2008.  There is a 2 pm symposium and an 8pm concert by renowned organist Ken Cowan.  The event is free.  

Here is a link to the event:

http://www.virginia.edu/music/pressrelease/07-08/organ032908.html

Here is a link to a description of the instrument from the restorer:

Cabell Hall was designed by Stanford White and completed in 1898.  The building includes an auditorium that seats 994 with a Skinner organ, a gift of Andrew Carnegie in 1906. 

Here is a 360 degree virtual tour of the auditorium on the Tuesday Evening Concert Series web site.

A job posting but not for a band

The church that I attend, Hebron Presbyterian, has a beautiful Taylor and Boody pipe organ that needs an organist.  

Here's the church web site advertisement:

Here is the Taylor and Boody web site about the instrument:

http://www.taylorandboody.com/opuses/opus_46.htm

The instrument is only the second one in the world to be built using the tuning system devised by J. S. Bach and "hidden" in the "squiggles" at the top of the first page of his "Well Tempered Clavier."  This was discovered by Bradley Lehman, and is explained on this page:

http://www.larips.com/

Here is a sound clip from the organ's dedication. It includes Walther's prelude on "Praise to the Lord The Almighty, the King of Creation", some congregational singing, Bach's prelude on the same tune, and more congregational singing.

Wonderful Christmas Concert

Again this year the Christmas Concert was absolutely superb. Thanks
to all 70 players who participated. Your gift of music to the
community is greatly appreciated. Thanks to St. Paul's United
Methodist for the use of their beautiful and acoustically excellent
sanctuary for our concert.

Rehearsals resume on January 7 for the Summer Season of concerts in
Gypsy Hill Park. We are actively recruiting in the percussion,
clarinet, and flute sections. We are starting on the summer concerts
earlier in the rehearsal season this year and including more review
nights in the schedule.

Thanks to each member who gives so tirelessly to the success of The
Stonewall Brigade Band.

Welcome new band members!

We welcome a number of new band members in our trumpet, clarinet,
trombone, saxophone, french horn, baritone, and string bass
sections. Several of the new members are from the Charlottesville
area, so there is a developing "car pool" for folks driving to
practice and concerts from central Virginia.

At the present time, we are strongly recruiting new members in our
flute, clarinet, and percussion sections. New members are welcome in
every section at any time. Besides the concert band, opportunities
exist for participation in our small ensembles.

Be sure to check the "band schedule" section of the band web site for
various ensemble performances, ensemble rehearsals, and the concert
band schedule.

Welcome, new assistant director

It is with great pleasure that I welcome Frank Sampson as assistant director of the Stonewall Brigade Band.  Frank is band director at Rockbridge County High School in Lexington Virginia and is a former drum major with the James Madison University Marching Royal Dukes.  Frank will be sharing the conducting duties on the band's 2007 Christmas Concert to be held on Monday, December 17, at St. Paul's United Methodist Church, Staunton.

Twentieth-Annual Stonewall Showcase of Bands is history.

The Twentieth-Annual Stonewall Showcase of Bands is now history.

Of all the Showcases we have had, this has to be the smoothest
ever! The kitchen crew, the press box crew, and the cleanup crew
had almost finished by the time the last bus pulled off the lot. The
weather was beautiful, and the event ran on time all day, with the
exception of a five-minute delay in the start of one class, which was
made up during the next break.

Scores are all available at www.stonewallbrigadeband.com/showcase.html 

along with a press release.

It is very notable that the top winning bands are all on a seven-
period day or an even-odd (alternating) block scheduling system in
their schools, and the lowest scoring bands are all on the four-by-
four block system. On a four-by-four block system the band members
get to be in band class three months out of the year and are off from
band for nine months of the year except for after-school rehearsals,
which have to compete with athletics for time and student
participation. The seven-period day and alternating block schools
allow band members to be in band class for nine months out of the
year, with obvious improvements in the tone quality, endurance, and
stage presence of the bands.

Special congratulations go out to Bath County High School Band.
They had fourth highest overall band score and the highest percussion
score of the day. This is an enormous accomplishment for a school
that includes only 333 students (according to Virginia Department of
Education Fall 2006 statistics) in grades 8-12 in a rural county
divided by mountains. They were the fifth-largest band at the
Showcase, eclipsing many schools with far greater enrollment. With
one band director teaching band in grades 5-12 in the two elementary
schools and one high school, this accomplished group of musicians and
their director deserve special accolades.

Additional congratulations, on top of years of accomplishment, go to
Charlottesville High School Band. Charlottesville has had only two
band directors since 1942! The band is a 26-time Virginia Honor
Band, and has appeared in Macy's Thanksgiving Day Parade, and the
Rose Bowl Parade. This is truly a class act. Brothers Vince and
Joe Tornello direct the band.

Thanks to all the members of The Stonewall Brigade Band and the
Staunton Recreation Department for an excellent job running the
Showcase!

Time counting trick for non-wind players and other cool stuff

This works for piano, organ, percussion, and strings while actually
playing. It can also work for winds when they are resting but not
when they are playing, as you will see from the method.

I developed this little system for myself, because as an organist, I
have to be very careful of how long to hold whole notes when playing
hymns for a congregation. There is a great tendency toward church
pianists and organists to "jump the gun" after a long note.
Sometimes this is caused because the congregation is mostly non-music-
readers and just guess at the rhythm rather than feeling the pulse
and reading note values. Then the pianist or organist "goes with the
flow" and you get a sort of random, vague tempo that leads to lack of
participation. An organist that wrote an article in "The American
Organist" magazine took Duke Ellington's "it don't mean a thing if
it don't swing" and made it "it don't mean a thing if they won't
sing." This can be a mind-altering thought for someone like me that
has been playing the organ for 50 years. A firm, strong pulse leads
to great group singing.

Here's the technique: With your mouth shut, put your tongue against
the roof of your mouth and then pull it away (but keep the tip of the
tongue against the roof of your mouth and only pull down the back of
your tongue) , like pronouncing the sound "ch." You'll hear a
clicking sort of sound in your own ears. This make a great "ersatz"
metronome that you always have with you. You can "tick tock" to your
heart's content and nobody will know. You can also use this
technique to practice subtle changes in tempo while looking at a
piece of music. That way you can learn just the tempo change on a
ritard or accelerando without having the actual manipulation of the
instrument as a distraction. It is also a good technique for "finger
practice" when you are looking at the music, doing the "fingers" on
your horn, but not actually playing. Adding the "tick tock" to
finger practice can reveal rhythmic irregularities or inaccuracies.
Think about the difference between an irregularity (pulse) and an
inaccuracy (note value). It is also good for figuring out when to
use an agogic accent. (Go look that one up.) (Here's a good
reference--piano based but also general:
http://davidkelseypiano.com/teaching/piano.html

One of the most disconcerting and jarring things you can do to an
audience is to rush. Have you ever climbed a staircase and found
that the top step was a little shallower (or taller) than all the
rest? Jars your teeth doesn't it... because it disrupts the rhythm
of stair climbing that you established on the first two or three
steps. Rushing a whole note is just as jarring.... or actually
rushing the note that follows a whole note. This applies to any
sort of music.

The "ch ch" technique I described above is also great for wind
players who are sitting there counting rests. It helps you keep your
count with the conductor's tempo. Of course, you have to pay
attention to three things... your own counting speed, the tempo set
by the conductor, and keeping track of where you are..and hold your
attention on all three. Frankly, I count on my fingers. Just press
one finger a little harder into your palm or onto your leg and you
can count on your fingers without anyone knowing you are doing so.
I start with the "pinkie" as one. The thumb alone is 6. That allows
you to get to 10 on one hand.

The "moral to this story" is to figure out what you want to be able
to do on a consistent basis and then develop a system for doing it
the same way every time... or adopt someone else's system after
trying it and finding that it works.

2007 Concert Season is now history

Our 2007 Concert season concluded on August 27 with the People's
Choice Concert. Overall the season was a great success and was
enjoyed by band members and audience alike.

Doing a dozen concerts in a row with all different music (except the
People's Choice Concert) is quite a challenge for an all-volunteer
group, especially since we do all the rehearsals in the Spring and
none during the concert season.

As director, it is my job to know all the music--tempi, entrances,
trouble spots, and things to say in 10 words or less to remind the
members of things to watch. One technique that I had forgotten and
then remembered and put to good use is the idea that correcting the
balance between parts in the band can go a long way toward improving
pitch (which is already very good) and rhythmic precision (which is
sometimes a problem with a large band when everyone is busy reading
the page.) There was a book and set of band exercises published by
W. Francis McBeth about 30 years ago that came to mind in August.
The quick fix was to have the band play a simple Bb concert scale
slowly while I listened from the podium. Then I explained which
sections needed to be a little louder, which a little softer, and
which were ok for the dynamic level. This was done first at forte
and then at mezzo forte. The results were dramatic! Balance,
tuning, and rhythmic precision all improved from good to great.

Another thing that really helped rhythmic precision was to add a live
monitor behind the band. We put one of my Peavey KB-100 keyboard
amplifiers behind the band and ran a mike line up front with the mike
at about eye level with the front row and just behind me. This
allowed the back of the band to hear the front of the band. The
chordal intonation locked in much better, and rhythmic precision
improved, plus we heard the woodwind sections better when they had
the melody and the brass were accompanying. Being able to hear the
front of the band helped the back of the band know when to adjust
their dynamic level from "lead" to "background".

We are now off for a month and will resume rehearsals on October 1,
when we prepare for our October 6th appearance playing "oompah" music
at the Frontier Culture Museum's "Oktoberfest."

Persistence and instrumental technique

In the last post I wrote about the Psychological concept of
Persistence... keeping a mental image of something after the
"something" is no longer seen or heard. The idea was that when we
play a note, then a different note, and come back to the first one
that the pitch must sound the same. (Notice I said sound the same,
not be the same, because listener perception of good tuning is
relative to the other notes being played at the same time.) We want
our listeners to "hear" us being in tune.

Now some things about keeping the pitch the same. There are certain
inherent problems "built in" to your arm, fingers, lip, brain and
instrument that you can easily overcome if you are aware of them.

Instrument by instrument:

Flute: Octave jumps can be tricky to tune. First the head joint has
to be tuned properly using the end cork so that octaves are in tune.
There is a mark on the cleaning rod that is supposed to be equal to
the diameter of the head joint at the embouchure hole. This is the
distance that the cork should be from the center of the hole, AS A
STARTING POINT. Real tuning is done by ear. Play just on the head
joint and then go up an octave. Do this 4 or 5 times and listen to
see if the octaves are in tune. Pulling out on the cork will widen
the octaves and pushing in will shorten them. There will be a point
where the octaves are in tune and the tone will be much clearer and
stronger. That's where you want the cork. After you have tuned the
cork, be aware of head position and air direction. Low notes--raise
the head and pull the chin back so as to blow down into the hole.
High notes, dip the head and push the lower jaw forward. Some
practice on octaves on your instrument will have you in tune in no time.

Trombone: The trick is in muscle control of your "slide arm." The
general tendency is to mis-play 2nd, 3rd and 4th position a little
too far out when coming from first position, and a little too far in
when coming up from 6th or 5th position. It's important to "land" at
the right place, no matter which direction you are coming from...
don't over shoot or land short. Play F,G,A,G,F,A,F a bunch of times
and you'll learn to nail 2nd position. You can make up your own
exercises for other positions if you think about it.

Clarinet and saxophone: The trick is to push the reed halfway closed
with your lower lip, so that the reed vibrates the same distance in
each direction... toward your mouth and toward the mouthpiece. To
figure this out, look at the mouthpiece from the side and see where
the mouthpiece curve away from the reed tip ends and the reed is
touching the mouthpiece. Look at your reed off the mouthpiece and
find the "heart." With the reed on the mouthpiece, looking at it
from the side, put your thumb on the heart of the reed and press
lightly and figure out how far you have to move the reed to move the
tip halfway to the mouthpiece. Then do the same thing with the
mouthpiece in your mouth. This is the starting point for good
control and will generally allow the instrument to play in tune.

Additional clarinet trick: If your high notes go flat just push up
on the thumb rest when you go higher. This will tip your head back
and create a bit more pressure on the reed, pushing the tip closer to
the mouthpiece. To get a faster vibration, the distance should be a
bit shorter for the vibration. This is the same principle as a
pendulum... longer=slower, shorter=faster.

Brasses: The key to good tuning is training your lip to play all the
notes. Try this: Start a buzz without your mouthpiece, starting
with as high a pitch as you can manage. Slowly let it "glissando" or
sweep downward to lower and lower pitches. If you hit a "dead spot"
these are notes where your lip really isn't trained to vibrate and
are notes that will have a fuzzy tone and be out of tune. Do this
exercise at a different time than when you play your horn. You can
even do it while driving your car (alone is better.) Start as high
as you can and slide down to a really "floppy lip" sound as low as
you can go. In a very short time you will find that your tone has
improved and so has your tuning.
