This tutorial teaches some possibilities to play 7/8 patterns on a handpan. (such as PanArt Hang, SpB, Halo, BellArt Bells, etc.)
In the first video the different patterns are explained, and in the second video you can see a composition based on those patterns.
The instrument in this video is an SpB made in Russia in F Integral tuning. Unfortunately I can not help you getting one of these instruments. Most handpans are more or less difficult to obtain, or have waiting lists. If you are looking for more info on how to acquire a PanArt Hang drum, Halo, SpB, Bells, Caisa or other handpan, check out the forum at http//www.handpan.org.
