I think the question of actually relating emotion to music is totally interesting. I believe that it is really important on some level, but it's also important not to impose your own emotions on some music that has its own emotions.

All these emotions are coming from one thing - sound. It's not coming from your experiences in life, your childhood. It's related to those things, but it's being triggered by the sound.

When you're listening to music, you listen to it with a friend one day and it sounds one way. You listen to it with another friend the next day, and it sounds a little different. Sometimes the greatest pleasure of listening is not the music that you're listening to; it's the person that you're listening to it with.

Even if you're a genius and you invent your own language, it doesn't become a language until there are people using it.

There is no guiding principle, because the work that is created in collaborations should be created from its own principles.

In a way, composing on the melodic level is an expression of a melodic truth, almost like a geometric truth. If it has clarity, other people will recognize it. There's no way of isolating it in a gallery on a white wall and saying, "This is a work of art. This is a mathematical proof."

The most appealing part is the feeling of learning something true - the pleasure of a truth. For me, that's mostly found in philosophical literature at the moment.
