% modification of the procedure "chordRootNamer"
%---- Definition of chord alterations -------

%----- markup commands to make it easier to write chords -----
%----- this section can be adapted as desired (I don't like "MI" and "MA", for example)

% for major chords, use "acMaj" to print a small "M"

(interpret-markup layout props
(markup #:super "M" #:super extension)))
% for chords with up to three alterations, stacked on top of each other

(markup
