I've listened to a couple of Leonard Bernstein's lectures, but I hadn't heard the one on Music Phonology - so I watched & it's good (just distracting that he constantly touches his nose). 

I watched quite a few jazz tutorials last year, but it was the ones on improvising with chords for jazz 'piano' that opened my eyes about tonality - fit right in with what Berstein got to at the end of his lecture. 

It makes sense that our bowed strings sound so great (strings a 5th apart) & maybe something to why I like MORE strings... but the Norwegians really got it right with all the extra sympathetic strings on the Hardanger fiddle - similar to Bernstein's demo, you hear more overtones! 

What I didn't realize was that lower notes have more pronounced overtones!  HOW COOL!  ...now THAT probably answers why I like lower sounds, especially people's voices (I still get unnerved when I hear guys singing soprano 🥴). 

Thanks for bringing this up - I'm sure you will enjoy your courses!
