I believe music has meaning and can speak deeply to subjects of importance or lightly to subjects of fun.
It has the capacity to confront us to think and feel despite our best intentions to push it away. I have been asked about my own pieces before, the instrumental ones, and what they mean (if anything).
The best I have come up with in answer is to say, “well they mean something to me, but it’s not all they could mean”. I don’t always know but I certainly feel deep meaning in playing and sharing them.
I have had others tell me what they think my work means too, and who’s to say it doesn’t mean exactly that. Overall it means something to the artist and the audience, what exactly we can only grasp at (though it’s absolutely worth reaching for).
