How to use timpani in a live orchestral piece? (I'm asking for the most fundamental knowledge)
I write scores for live symphony orchestras (which basically means the scores can entirely be played live by a normal-sized symphony orchestra), and a problem comes about: how to write the timpani part(s)?
My knowledge for it is almost zero, so could somebody please tell me how many timpani are usually selected and which ones are most commonly used in a live orchestra? How many players play them?
I know that the answer may vary based on different orchestras, so just tell me the MOST COMMON situation, or if there isn't one, a range of choice among which I can choose from. Thanks!
