We are just about to get our Training Band started and the conductor has asked me to get them some music which I'm told is called The Crotchet Factory - comes with all treble clef parts but no bass trombone. My problem is what is it and where do I get it - have searched on Google and that comes up with Mostyn Music and Just Select but I can't find the details. Is this a selection of suitable music for training bands or the publisher or just individual arrangements for a training band? Would I then need to get a selection of separate pieces for them? Anyone used this music that can point me in the correct direction? Thanks in advance.
