I'm taking up the autoharp (OS 21-chord) late in life; no intention to perform in public, just with the guitarist son for the grandchildren, probably. Is there any reason why I (right-handed) shouldn't learn to play lap-style, playing the strings with the left hand and the buttons with the right? At least I'd be able to see which buttons I was mis-hitting! Also, my right hand being stronger is more likely to keep the strings properly damped....
