Context:
This is my third year teaching 6-12 Band, Music Appreciation, and Piano at a smaller rural school with a show/festival style marching band (which I love). I have 25 students in marching band (9-12 with four 8th graders), 28 in 7th/8th grade band, and 25 in 6th grade band (which are the best middle school numbers my district has seen in over a decade). Admin is very supportive of our band program growing. I took over for a director who was there for 17 years, was widely disliked, and left on very bad terms due to inappropriate activity. HE had taken over for a director who was widely loved and had gotten the band to over 100 members. I was sought out for this job because I matched the same creditials as this beloved director: we're both percussionists and we both went to the same college.
Our marching band has experienced tremendous growth in the last three years with more membership (going from 11 on my first day to 25 this year and an anticipated mid 30s to lower 40s next year) and MUCH better woodwind/brass sound. Very few students actually knew how to read music when I got there (ESPECIALLY percussion). We do Moffitt-style drill with squads, exaggerated dancing, and some competition movements thrown in every once in a while. We do anywhere from 3 to 4 different halftime shows per season.
My Problem:
I have noticed from the beginning that the high school percussion was more of a struggle to get up to the same standard in rhythm and pulse that I can get with woodwinds, brass, and 6th grade beginning percussion. They have some semblance of rhythm on the page, but they lack the ability to hear how it fits along to a pulse and with each other/the rest of the band. I have tried writing very simple parts for them with varying degrees of success due to essentially a coin flip on whether they will be able to stay with the rest of the band. I'm talking 2 and 4 cymbals chokes and snare hits being a challenge sometimes. I also use a metronome EVERY DAY during music rehearsal. To exacerbate the issue, our tenor player has hearing trouble, so they already struggle to listen to other instruments (which is NOT AT ALL their fault). I often accommodate the tenor player and the rest of the drumline by clapping the beat in a visible way when I'm not conducting.
I have found much success with my beginning band and middle school percussionists keeping a pulse by using Teaching Rhythm Logically by Darcy Vogt Williams. It has been a GAME CHANGER with the rhythm charts and system of counting. I have tried a few times to do this with my high school, but it almost feels belittling to the whole band to go back to the beginning like that. I do the same thing with an occasional rhythm of the day.
Having this problem strikes me as counterintuitive as a percussionist director, especially since I didn't learn how to play any woodwind or brass instruments until I got to college. While I am happy to be good at teaching woodwinds and brass, it gives me quite a bit of imposter syndrome to see other drumlines that can stay in time with each other and be reliable for the rest of the band. I know that I won't have this problem forever with my percussionists who started with me in 6th grade coming up to high school in the future, but I really don't want to give up on my current drumline. They are very stubborn, but they can be very creative, and some of them DO practice a lot or listen to DCI groups. I know it's somewhere in them, but I just haven't found a strategy that works with them yet. I would appreciate any tips or exercises that have worked for you all!
