Seems obvious, doesn't it? Not nearly as much.
Too often we feel we are forced to play something which we have no respect for, which we wouldn't cross a street for, something which we ourselves wouldn't want to listen to, never mind go to the concert to hear.
But if we switch this around, if we really think about what it is we love in these pieces, then maybe, just maybe our art can make an impact we seek.
Playing what you love isn't sufficient. Loving what you play will make a difference.
