Who designed the template? Do they know what a brass band is? It took Sibelius several versions to finally get it right - any chance that we won’t have to wait several years to get this right? Instrument formatting for standard British Brass Band should be as follows:-
Soprano Cornet Eb
Solo Cornet Bb
Repiano Cornet Bb
2nd Cornet Bb
3rd Cornet Bb
Flugelhorn
Solo Horn Eb
1st Horn Eb
2nd Horn Eb
1st Baritone Bb
2nd Baritone Bb
1st Trombone Bb (Treble clef)
2nd Trombone Bb (Treble clef)
Bass Trombone
Euphonium Bb
Eb Bass
Bb Bass
Timpani
Drum Kit
The spacing shows how the instruments in the score should be bracketed.
