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 BasisTrolley helps students or teachers move around the larger keyboard instruments with ease; the height and width are both adjustable to fit any Orff keyboard, and the four large wheels let the instrument roll easily to any location. A BasisTrolley Adapter must be purchased separately and attached to the desired instrument in order for it to connect to the BasisTrolley.
