My preference is to the 15 Bar harps. Diatonic with majors in the front row, minors only in the back row. My fingers and hands are too big for comfort on the 21's. Also due to physical limitations my fingers won't bend well enought for a button rank of three rows. I also like the additional playing area in the 15 bar harps. But these are personal prefences, not God,s law.

Nathan is very correct about trying MANY different chorded harps. I like George Orthey's, Kieth Young's and the older Autorino harps.
