General Copyright Concepts:
Music copyright:
There are seperate copyright issues concerning the musical composition itself and a recorded or printed item (score, CD, digital file, etc.) produced from the work. The composition is considered to have its own creator, dates, and rights, while the produced item (score edition, CD, etc.) will have specific rights associated with it. For example, a Mozart symphony may be in the public domain, but the score edition published last year or a particular recorded performance is not.
Often a copyright notice will be located either on a recording or on the sheet music for a composition.
