Really interesting in this thread about how so many see images or hear voices. I always have strong threads of music, always available at any moment. I bet all musicians have this. I used to wish when I was a child that I could jack my brain to a stereo system for instant playback and bypass the effort of writing things down.
Ouch my poor brain went into shock reading that! I'd done all I could to forget schenkerian analysis and now it's all flooding back. Aside from that, nice intro to helical harmony.
