Deep thoughts are welcome! I find this topic is connected to everything, so let your thoughts fly.
To answer your question: many years ago i had a band and we improvised all the time. we were 6, most of them real musicians, i started as a singer but then bought a bass and just played with it. so i guess i'm a self-taught bass player. it kind of started even more early, when we sat around in our living rooms and began to record music, improvised on instruments or anything else that made a sound. this somehow became a real band with amps in a room and very loud!!
in my opening post i mentioned: "nada brahma - the world IS sound" by joachim ernst-berendt, an old german radio feature, which i would recommend for you.
i think it adresses everything you asked and mentioned and is a mind-blowing, marvellous feature with so much information that will take your thoughts to a new level.
sadly i couldn't find an english version, but maybe you can find something similar to it?
for the german speakers i finally found this:
Nada Brahma - Die Welt ist Klang 1/4https://www.youtube.com/watch?v=qpjpvjLRd0E&t=1955sSo just an example out of it:
at around minute 17 he explains that when singing "ohm" the whole body resonates and shakes and that from this "ohm" out of tibet, the christian "amen" as just a stronger vocalized version of "ohm" became..
and he the then he fades tibetanians monks chanting "ohm" into a christian choir singing "amen"...wow!
So the feature is about
sound as the essence of life.
in the feature you will hear about language, musik, harmonys and the connection to the mathematics of harmony and the planets, mantras and so much more, and with so many musik and sound examples.
in this, the first part, is musik by:
ali akbarkan, a choir tibetaninan monks, hendel, johann sebastian bach, peter michael hamel, pink floyd, a balenesian gammelan orchestra, ben webster, john coltrane, santana, don charie, a brasilian makumba ritual, duke ellingtonand this is only the first part.
at around minute 47 you can hear pulsars, the rhythm in the universe...
