Love this tune … makes me want to fire up one of my synths too and play along …
Speaking about polyphony … it’s less about having the opportunity to hit more than one key at a time and play chords, it’s much more about the sounds.
As an example in the words of a jazz-piano teacher, who I watched the other day.
She was talking about students, improvising, and musical expression. She complained about other teachers, who gave lessons on too much theory, but not the feelings of music. Often students learn the theory, she said, and play even complex scales all day long, even virtuoso, and think this may be a way to achieve “real improvisation”, but are frustrated, because it doesn’t really work. As an example she said, she often asks a student what is an Am7 or a Bb9aug etc. and always she gets the correct answer of the single notes to be played … BUT she never got the answer … this is a chord or a progression generating this or that particular “feeling”.
IMO polyphony generates sounds and hereby feelings, which we can’t achieve with a single “solo-instrument”. It takes a couple of voices, which are set at a particular distance, detuned, different in timing, like the string section in a classical orchestra. I prefer a polyphonic instrument to achieve this rather to use a couple of solo-instruments, which are combined in the propper way. I think, I am just too lazy to get them all playing as I want
