 In this case, a timpanist can hold two sticks in one hand much like a marimbist, or more than one timpanist can be employed.In his Overture to "Benvenuto Cellini", for example, Hector Berlioz realizes fully voiced chords from the timpani by requiring three timpanists and assigning one drum to each.He goes as far as ten timpanists playing three- and four-part chords on sixteen drums in his "Requiem", although with the introduction of pedal tuning, this number can be reduced.
