Excellent show! The greatest takeaway point is that linear and non-linear processes are often subject to the "grey areas" fed by human psychoacoustic Frames of Reference, wherein sensory discrimination breaks down. This happens within all areas of music, by the way - what distinguishes a Rhythm from a Tone when the Tempo of a piece becomes significantly faster than the "ear-brain" can track?
What a wonderful accidental find. I was something of a trombone prodigy in high school and when my teacher demonstrated the playing of a trombone harmony I became obsessed with mastering the art. What a lot of time I spent trying to put the trombone’s note out of mind while concentrating on singing/humming another tone. I achieved it but now at age seventy I’ll health prevents me from playing the ‘bone however what a wonderful memory you’ve stirred up for me. Thanks.
