Bards of course have a very long history, as do all oral storytellers, but in your fictional world, how are the musical arts celebrated? What kinds of music does your world have - classical only (as we would know it) or across the board with all genres from rock to ballads and so on? What status is held in society by musicians and composers?
I don't have a favourite composer. I just know what I like when I hear it. Do your characters react similiarly? Or are they antagonistic to music or a specific composer and, if so, why? All worlds have celebrations and feasts and music usually features strongly so what goes on in your fictional settings here? You could have a world without music, which to me would seem utterly soulless but then that is almost certainly the point of your story!
