Re: Fwd: re: automatic beaming behavior

[Reilly Farrell]

Thank you for your responses.  In this case, we're looking to set up beaming rules that LilyPond does not follow by default (such as grouping consecutive eighth notes in pairs of two when in 4/4 time, rather than groups of four).

David, your solution seems just like what we need based on what I've read in the documentation.  Right now, though, I'm receiving the following error message: 

error: wrong type for argument 3.  Expecting list, found 2

    2,

      2,2,2 % beatStructure

../../../road-map-score-block.ily:20:6: error: syntax error, unexpected ','

    2

     ,2,2,2 % beatStructure

etc.

Is there something I've overlooked in the formatting?
