In the 1920s, Carl Orff (of Carmina Burana fame) developed a method of teaching children about music that focuses on treating music just like the spoken word - starting with just a few notes and continually adding complexity as time passes. The Orff method necessitated a collection of simple, non-intimidating musical instruments to teach the foundations of western melody and harmony in a group setting - what is more well suited for the job than drums and rudimentary keyboard percussion instruments?
The Sonor Orff Meisterklasse Chromatic Rotary Timpani uses a tried-and-tested system of central tuning. This 16" drum has an approximate range of C - G and has a calfskin head (which is less resistant towards changes caused by humidity but provides a warmer sound). The Sonor Rotary Timpani are precision tuned by rotating the drums and are designed for sound projection by having none of the hardware or tuning mechanisms touching the shell of the drum. This drum has three height-adjustable legs and would be a good part of any elementary music class.
