I’m not understanding this reasoning at all...what are you guys talking about..."for the beginner" or.."too advanced in depth and nature, "talking a different language"
....what the heck does that all mean....when we are talking about music!
Music, and John Coltrane could play some great music, is what makes the listener enjoy the experience of listening. Personally, ALL music allows me to enjoy the experience...and that is what i think the great players, like John Coltrane could accomplish. So, IMO, there is NOTHING to understand when you listen to John Coltrane, or any other good-great musician, you will enjoy the experience. If you don’t enjoy it, that doesn’t mean you don’t understand it...it just means you don’t like it...and there’s nothing wrong in that!
I hope this makes sense coming from an ex-pro musician.:0)
