RE: transpose from "treble" to "bass"

[Fairchild]

Andreas -

Starting by keying ly from a printed score in both bass and tenor clefs
(DUAL), it was converted to all bass (BASS), then to treble (TREB), and then
transposed to treble in an easier key (TRAN).  This code demonstrates with
one line for each.

        \relative c' {

When I think I'll be printing up different transpositions like this I try to
prepare for it when I input the notes.  For example: music = \relative c' {
  c d e f g a b c
}

\score {
%  \transpose c c {    % use this line for treble clef Bb
  \transpose c bes,, { % use this line for bass clef C
%   \clef G            % use this line for treble clef Bb
    \clef F            % use this line for bass clef C
    \music
  }
}


First I defined the music.  Then I set up a couple of switches so I can
easily change between transpositions.

Hope this helps.
