So, I am curious as to the purpose of playing pedal tones on brass instruments, and specifically the trumpet.
To clarify, when I say pedal tone, I mean a note that is off the bottom end of the useful range of the instrument....it sounds like a growl more than anything....far lower than a low F# on the Bb trumpet.
My son's marching band brash-tech really pushes this across the entire brass horn line. It's pretty much trashed by son's upper range on trombone and I've noticed that the brass section seems to have lost all of the upper range. I doubt if any of the trumpets can sustain a high C more then a few seconds. They play these at the end of their pre-performance warmup... (not a warmdown). They are played at various dynamic levels (up to ff) and articulations (up to fast 1/8th notes)
I've consulted with some others professionals and forums and with the exception of the DCI-crowd, no one seems to like them for this age group and most don't like them at all. The DCI-crowd sites that is it "warming-down", "for balance" and "to hear each other".
The directions given to play these notes is to "open your embouchure and blow down as hard as you can". After consulting with my son's trombone instructor (DMA performance) he advised my son to stop playing them all together ... which he has and his upper range has recovered a 4th so far.
So ... what are they for?
Thanks in advance for the input!
