The way I see it, music (like everything else?) is empty of inherent existence. This is not obvious. Plato and Aristotle believed that harmonies and rythm express/represents "charachters". Contrary to the Greek champions, I do not think musical harmonies and rythms express or represent anything in and of themselves. The "meaning" and interpretation of music is dependent on causes and conditions, dependent on its parts, and imputed by mind. Music is empty.
My question is how this emptiness of music can be incorporated into my practice. In stead of giving up music because I want to spend my time with meditation, I am wondering if the emptiness of music might in stead and in addition be used as a "mantric device" in mediatative practice.
Here's the idea. I play bass. Me and my fellow musicians love minimalist repetition. Some say practicing an instrument is boring because you have to to the same thing again and again, but I don't agree. I think playing the same bass line over and over (alone or with others) is giving the same experience as meditation with mantras. When you play a simple line hundresds of times, you don't have to think about playing. And after a while you don't know where the line starts and ends, it's circular. The mantra is in my fingers and not my mouth. In the end, both mouth and fingers are in the mind anyway.
It may be a long shot, but I wonder if this way of using repetition is used as a meditation device in any Buddhist practices. What schools of Buddhism is most open to this kind of idea?
