An easier way to do this is to just add it to the top of
predefined-ukelele-fretboards.ly, in this fashion:

 #(define-public ukulele-tuning '(9 4 0 8))

Yes and no.  If you look at the chord notes that show up on your music,
you'll see that the c chords are an octave lower than the a and b chords
(because octaves are defined to *start* with c).  This means that the notes
of those chords are too low for the ukulele to play; hence the warning
message.

However, there appears to be a bug; the chords are getting properly looked
up so the message shouldn't be printed.  I'll try to resolve that.

In the meantime, 

\transpose a c' \myChords

instead of 

\transpose a c \myChords

will get the chords within the range of the ukulele and avoid the warning
message.

Thanks,

Carl
