"Execution is making something." So I guess for you that "something" has to be tangible. How would you characterize a musical composition.. could that be art?

"Execution is making something." So I guess for you that "something" has to be tangible. How would you characterize a musical composition.. could that be art? After all, a musical composition is nothing without being performed -- either on real instruments or in a sheet music reader's imagination. But that performance is not in the composition, so one could argue the composition itself has no execution and therefore by your definition of art a musical composition is modern art. Yet there are plenty of pre-modern compositions, arguably without execution either.
