TromboneChat

Thinking about doing an on-line non-accredited 12 week arranging course here. Partly aiming to broaden my overall skills and knowledge and also to smarten up my three part horn section arrangements in a 10 piece covers band.
Did some research online but still undecided. Anybody have any first hand knowledge or experience of this part of the music school or similar alternatives?

Useful links, thank you Bach. I have used musescore for a few years now and find it really useful for what I do. It may be the sources you recommended are all I need right now. Certainly a lot cheaper and no time pressure.
