The syntax is
The syntax is


\scale-diagramm #'( (string1 fret1) (string2 fret2) ... ) #notesinscale #size
\scale-diagram #'( (string1 fret1) (string2 fret2) ... )
                #notes-in-scale #size


For example for a c pentatonic scale (first six notes)
As an example, here is a c pentatonic scale (first six notes).


\scale-diagramm #'((5 3) (5 5 ) (4 3) (4 5) (3 2) (3 5)) #5 #1.5
\scale-diagram #'((5 3) (5 5) (4 3) (4 5) (3 2) (3 5)) #5 #1.5


you can wrap this up in a markup command for building up a list of scales
You can wrap this up in a markup command for building up a list of scales as follows


cpenta = \markup \scale-diagramm #'((5 3) (5 5 ) (4 3) (4 5) (3 2) (3 5)) #5 #1.5
cpenta = \markup
            \scale-diagram #'((5 3) (5 5) (4 3) (4 5) (3 2) (3 5)) #5 #1.5

c^\cpenta d f g a c
