Subject: RE: Technique: Piano Accordion for The Recycled Muso
This section about autoharps also demonstrates how you use the I IV V buttons to harmonize against a scale.

What's the difference between a chromatic autoharp and a diatonic autoharp?

a five-note major scale, played both up and down. To play this scale on a chromatic autoharp requires the I, IV and V chords of the key

Note the I V I IV I cord progression for the first 5 notes of the scale. It is left to the student to work out the rest of the scale :-)

The autoharp and the Stradella Bass Piano Accordion are closely related in technique, due to the same music theory underlying them. If you play one, you can rapidly transfer to the other, due to the similarities.
