Re: Shortcut for epeated chords?

[Mats Bengtsson]

If you find the \repeat unfold syntax too long to type in, you can easily
defined a macro with a shorter name:
rr = #(define-music-function (parser location num music)(number? ly:music?)
#{ \repeat unfold $num $music #})

The only complication is that you have to add a #-mark before the
number that indicates the number of times the pattern should be repeated.
Example:

\relative c'{
\rr #5 <c e g>4 \rr #2 c8 \rr #6 r4
\rr #2 {c e d g, }
}

When it comes to extending the syntax, you have to be careful and think 
about
all possible side effects before doing such a change.
