Editing Timpani (section)

=== Other tuning mechanisms ===
A rare tuning mechanism allows the pitch to be changed by rotating the drum itself. A similar system is used on [[rototom]]s. Jenco, a company better known for [[Percussion instrument|mallet percussion]], made timpani tuned in this fashion.

In the early 20th century, Hans Schnellar, the timpanist of the [[Vienna Philharmonic]], developed a tuning mechanism in which the bowl is moved via a handle that connects to the base and the head remains stationary. These instruments are referred to as ''Viennese timpani'' (''Wiener Pauken'') or ''Schnellar timpani''.<ref>[https://web.archive.org/web/20170430020152/http://drtrumpet.eu/MB-PDF/2001e_MB_ISMA_timpani.pdf Vibration patterns and sound analysis of the Viennese Timpani]. Bertsch, Matthias. (2001), Proceedings of ISMA 2001</ref> [[Adams Musical Instruments]] developed a pedal-operated version of this tuning mechanism in the early 21st century.
