Obviously you need more than pure ideas, since art is about communication of ideas, not simply the formulation of them.
Exactly, and thatĀ“s why I think you need a composer AND a performer, they depend on each other. A composer without a performer is nothing. If you do that yourself, fine, but youĀ“re simply taking over this other job.
Performers overpowering the composer is simply bad taste and a disgusting egoistical attitude, but I donĀ“t feel that question brings us closer to an answer, what music is.
And, besides that, there are also performing composers out there which, as performers, overpower their composing part. But thatĀ“s because the composer part is so weak... [:D]
