I thought I may as well go straight to the source and ask percussionist. I'm a composer by nature, but I have a distinct problem. I emailed a symphony orchestra timpanist my question and they haven't gotten back to me in over three months. The question really is a simple one. When using pedaled timpani, when pressing the pedal, at what interval does that raise the pitch?
Thanks in advance all you percussionist.
I've played percussion only rarely, but I do have an excellent book, Blatter's "Instrumentation and Orchestration", which lists timpani characteristics as follows:
Sizes .... Range ... Comment
32, 30 .. D - A .... from below bass clef to A space
29, 28 .. F - C
26, 25 .. Bb- F
23 ........ D - A
20 ........ F - C .... piccolo timp; top note is middle C
The pedal moves a pointer over a scale that indicates the note that will be produced, provided the taps (turnscrews) have been adjusted correctly. Blatter notes that the best sound is produced at the middle of the range. At the top it is "hard and pingy"; at the bottom it is "long and rumbling" and "the attacks sound dull..".
If you are writing for a particular ensemble, ask them what sizes of timp they own.
