Hi,

don't confuse \transposition and \transpose. \transposition sets the
transposition of the instrument playing. This is used for getting cue
note transpositions and MIDI output correct. \transpose changes the
pitches of a music expression. The above was interpreted as


voiceTrombone = { \transposition bf }

\relative c' { .. }

\score  {
  << .. >> }

which effectively puts two \score blocks in a \book.
