A timpani concerto is piece of music written for timpani with orchestral or band accompaniment. It is usually in three parts or movements.
The first timpani concertos were written in the Baroque and Classical periods of music. Important concertos from these eras include Johann Fischer's Symphony for Eight Timpani and Georg Druschetzky's Concerto for Six Timpani. During the Romantic Period, the timpani concerto was largely ignored. The timpani concerto was revived in the 20th century and the timpani concerto repertoire increased significantly.
Timpani concerto set-ups can range anywhere from a normal set of 4(32", 29", 26", 23") to 16+ Drums, some of which are smaller than 20" or larger than 32".
