What is the mark of an expert timpanist?
Because of its sense of presence as a large musical instrument, you might think the timpani requires great strength to play, but since the instrument is large and made of material that easily reverberates, a large volume can be efficiently created with just a small amount of force. The important thing is not to disturb the vibration of the head and body. The player tries to create vibration as naturally as possible and play easily. Therefore, it may instead feel more difficult and require playing with sensitivity when creating soft sounds.
