Let’s set the scene: one of my fave songs starts in F# minor, flirts with F# mixolydian, and then starts the chorus firmly in F# dorian. I’m currently sifting through 16 songs like this to figure out which to put on the album, plus experimenting with harp accompaniment. My head is MELTED! Fortunately a few years back I made this quick-reference table for a workshop on trad accompaniment. I hope to goodness I get this done ASAP, and here’s hoping the table might help you too some day!
