Some of the top bands have an appointed "composer in residence" (Black dyke even two I think). How does this usually work? Does the band get the prvilege to premier all pieces by the composer if they want? Or should the composer write a number of pieces for the band (e.g. 1 per year)? Is their money involved in this (e.g. the band paying the composer a fixed anual amount), or is this more of a "prestige" thing, where the composer is trying to get more of his pieces sold by linking his name to the band?
