Great question. I'm not a musician -- I can't read a note, though I'm pretty sure I understand the concept. I think music comes of it's own, but it's origin is the material plane. It's the body's expression. It comes from depths, certainly, but it just doesn't affect me in what I would call a spiritual way. I think it's an expression or communication directed TOWARD the diety, which is sometimes expressive of what I'm feeling or emoting and sometimes not. Deep calleth unto deep . . .
>> . . . does the ego furnish or enfluence the lyrics?<<
I probably listen to music for pleasure once a week. All kinds. But rarely do I listen to music with lyrics I can understand. I describe most lyrics as "spell casting." It goes out rather than up. Now that you mention it, ego "speaking" works pretty good too. As manipulable as instrumental sound is for the musician, it remains just sound to me, worshipful or decadent, pleasurable or jangling, without the words. Black Spiritual/Gospel is one of the exceptions, as well as many more women vocalists than men.
Just my two cents.
Ps. I also rarely read or write and listen to music; yet I can work with numbers just fine. Something happens when words are added to the mix.
