Polymetric math

[David Santamauro]

Hi,

I’m typesetting an ensemble piece in 4/4 where one instrument goes to 6/4 – basically short-hand for not having to write two groups of quarter note triples for a longer duration. If I follow the documentation, it should be (according to the math): 2/3 * 6/4 = 12/12 (4/4). But the following doesn’t work:

 

\version "2.22.2"

 

\include "english.ly"

 

\relative <<

  \new Staff {

    \time 4/4

    c'4 c c c |

    c4  c c c  |

  }

  \new Staff {

    \time 4/4

    \set Staff.timeSignatureFraction = 6/4

    \scaleDurations 2/3

    c4 c c c c c

  }

>> 

 

This is my first sojourn into polymetrics with lilpond, so any rudimentary help would be appreciated.

 

Thanks
