A set of 5 Adams Schnellar Timpani crafted to emulate every tiny detail of the original pair hand built by Hans Schnellar and used by the world famous Royal Concertgebouw Orchestra in Amsterdam. Schnellar built his timpani in the Viennese tradition. A unique egg-shaped bowl, with only three legs, enhances the tonal character of a unique tuning system. To change pitch, the calfskin head and tension rods are stationary, while the bowl itself moves vertically, eliminating the counterhoop. Calfskin heads feature a claw tension system to help produce the pure tones of the shell. Includes a new set of Kalfo, hand-cart for moving timpani, flight cases.
