I've read piano no mori, nodame cantibile, nana, kiss, one, beck

I want something like piano no mori, or beck. A manga that is about a musician whos either disinterested in playing for others deciding to play/being forced to(in piano no mori's case) or a musician who discovers his/her talent for music and decides to develop it(like in beck's case).

I'd prefer the manga have romance but if its not possible then fine. and the longer the better.

Feed your head.

La Corda D'oro seems like what you're looking for.

I second la Corda. Also Venus Capriccio is all about pianos (its a shoujo romance)

Me & the Devil Blues.
