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
