In *classical* guitar-music, there is a finger augmentation called a "guide finger" indicating left-hand shifting. Nick Payne uses a mechanism based on the glissando.
I found this code written for a finger shift on a violin, which I like because it handles finger location and color, etc. However, for guitar, there are 3 kinds of finger shift: up, neutral and down, corresponding to about 30 degrees up, flat and 30 degrees down for the "-" character. So I can't make the changes to do what I want. 8-( I have sketched out what I would like, which is 2 default parameters, the guide character and the rotation amount, and to rotate this character before concatenating it with the string number. Any help would be greatly appreciated. ============================================================================ \version "2.14.2" gn = #(define-music-function (parser location fingering) (ly:music?) ;; #:properties ((guide-char #x2013) (rotate-guide 0)) (let ((music (make-music 'FingeringEvent)) (finger (ly:music-property fingering 'digit))) (set!
