Re: constructing a jazz piece

Hi Bernie,

Your code adds the \global in its own (implicit) Staff:

>          \new StaffGroup = "horns" <<
>      \global
>        \new ChordNames = "trpchords" \transpose c d {\harmony}

is the same as

>          \new StaffGroup = "horns" <<
>      \new Staff \global
>        \new ChordNames = "trpchords" \transpose c d {\harmony}

You need to COMBINE the global stuff with some other staff's music --  
see the trumpet staff in the attached (modified) code.

Hope this helps!
Kieren.

\version "2.11.47"
global =
{
        \time 5/4       \set Score.markFormatter = #format-mark-box-letters
        \tempo 4=108
        s1^"Intro - open" s4 | s1 s4 |
        s4 \mark \default s1 |
        \repeat unfold 7 { s1 s4 } \bar "||"
        s4 \mark \default s1 |
        \repeat unfold 7 { s1 s4 } \bar "||"
        s4 \mark \default s1 |
        \repeat unfold 6 { s1 s4 } \bar "|."
}
harmony = { c'' }
trumpet = { c'' }
tenorsaxone = { c'' }
trbn = { c'' }
piano = { c'' }

%% and then later on in the score block

\score
{
        <<
                \new StaffGroup = "horns"
                <<
                        \new ChordNames = "trpchords" \transpose c d { \harmony 
}
                        \new Staff = "trumpet" << \global \trumpet >>
                        \new ChordNames = "tenorchords" \transpose c d { 
\harmony }
                        \new Staff = "tenorsaxone" \tenorsaxone
                        \new ChordNames = "chords" \harmony
                        \new Staff = "trbn" \trbn
                >>
                \new StaffGroup = "rhythm"

                        \new PianoStaff = "piano"
                        <<
