Re: Auto beaming in unmetered music

[Trevor Daniels]

Hi

The easiest way to do this is to set measureLength and beatLength 
explicitly (as you've begun to do), but for them to be effective you 
need to either

a) revert any autoBeam settings that apply to the time signature in 
force (here the default 4/4), as explained in Notation Reference 
1.2.4 Setting automatic beam behaviour, or

b) use an uncommon time signature that has no autobeam settings, and 
prevent it being displayed.

Using (b) is easiest, as follows

...

notes = \relative c'' {
\clef treble
\override Score.TimeSignature #'stencil = ##f
\time 7/8
\key g \major
\cadenzaOn
\set Score.measureLength = #(ly:make-moment 1 4)
\set Score.beatLength = #(ly:make-moment 1 4)

c8 fis c a c e \bar "|"

...
