One of uncler things is a definition of music, though not fatal.

Music is a vibration of air, to reach eardrums within ears signaling brain
firmware, which is reproduced by player(s).  Music ends when a composer
complets a score for publishing.  What is a role of player? Some players
say players are adding a part of composer's role.

Comoser's role on music         C1
Player's role                   R1      +       C2
where
composing contribution:         Ci
reproducing contribution:       R

listner's contribution:         none, except financing both

Why C and D divide many times? Listen to Adam Smith.

Where is music, then? In listner's mind? On score? On CD(with player)? Or
all of them.  Or only in a process of air vibration, disappearing soon....
