Re: Shortcut for epeated chords?

[papa.eric]

\repeat is nice for true repetitions, but if I have various patterns using the 
same chord with different durations, and some ties or accents or different 
beaming or slurs, it does not work. Only the notes (pitches) really are 
repeated.

random example: c8 Y Y Y->~ | Y( Z) Z4_. | c8 X-> X_. X16 e16 | r8 ...

where X, Y and Z are big chords and there is no "true" pattern you could 
generate just changing the pitches... and there are many different chords so 
just putting X Y and Z in macros (\X ...) is not enough. How to not 
cut-and-paste in that kind of situation? (the result is hard to read).
