OK, let's try once more. :)
I promise it'll work this time:
\score {
\relative c' {
\tempo 4 = 60
c4 c c c
c4 c c c
\context Timing
\applyContext
#(lambda (ctx)
(let ((wholes (ly:context-property ctx 'tempoWholesPerMinute)))
(ly:context-set-property! ctx 'tempoWholesPerMinute
(ly:moment-mul wholes
(ly:make-moment 4 3)))))
c4 c c c
c4 c c c
}
\midi {}
}
Cheers,
Neil
