Schopenhauer's Song of the Heartstrings and the Emotions

Schopenhauer describes the peculiar nature of song as follows, and this is in world as will and representation. It is the subject of the will, i e, his own volition, which fills the consciousness of the singer,. often as a released and satisfied desire, joy, but still oftener, as an inhibited desire, grief. So that's what schopenhauer sang. Here to interpret it in the way nicha understands it, and ho he's presented it so far, there is a contradiction in the phenomenon of song because they're seemingly engaged in an art which plays upon the heartstrings and emotions.
