"Cumin Bob” tuning for 10-hole harp

NAME: “Cumin Bob” tuning for 10-hole harp BASIC CONCEPT: This tuning is designed especially for single-note and octave-split play. I think it would be especially powerful if set up as low possible. In this example, which is intended for play in the key of G major, the pattern is to have a Bb major ...
