Hi, Diane!I am a fan of a three-row chord set-up, majors in the middle, sevenths toward the treble, minors toward the bass. I have two chromatic 'harps-- one with 21 chords and one with 15. My 15-bar 'harp is does not completely comply with the majors in the middle, sevenths on top, minors on bottom but the arrangement demonstrates a logical compromise because it's based on the circle of fifths.Sevenths toward the treble side: C7, G7, D7, A7, and EMajors in the middle: Bflat, C, G, D, AMinors toward the bass side: Fmaj, a, e, b, fsharpYou can play most of an A chord by pressing A7 & Aminor at the same time; I'd rather have an A bar, though.The disclaimer to all this is I am far, far, far from expert on autoharp. I'm a strummer and by-ear player. Autoharp music theory discussions cause my eyes to glaze over. A weakness on my part that I'm willing to live with. LOL
