When I did this post, I used the Giant Steps (Coltrane) progression as harmonic path, in this way:
(setf
harmpath '((h (b3 maj7) (d3 7))
(h (g3 maj7) (bb3 7))
(h (eb3 maj7) (eb3 maj7))
(h (a3 m7) (d3 7))
(h (g3 maj7) (bb3 7))
(h (eb3 maj7) (gb3 7))
(h (b3 maj7) (b3 maj7)) (h (f3 m7) (bb3 7))
(h (eb3 maj7) (eb3 maj7)) (h (a3 m7) (d3 7))
(h (g3 maj7) (g3 maj7)) (h (cs3 m7) (fs3 7))
(h (b3 maj7) (b3 maj7)) (h (f3 m7) (bb3 7))
(h (eb maj7) (eb maj7)) (h (cs3 m7) (fs3 7)))
But in the resulting score, the chord symbols won't show.
I have some questions:
1) How to make the chord symbols appear ?
2) How to make my own custom chord symbols ?
3) Can I make associations of chord symbols with specific sets of notes ?
4) Can I display chord symbols over a melody with a Hidden Piano Part playing them ?
All the best !
