Rick Beato has a number of really cool videos on everything that’s music-related posted on Youtube (hence the appropriately named channel title “Everything Music“). You can find videos where he talks things ranging from music theory (such as complex poly-chordal/modal harmony) to studio/recording-related topics.

I’m just searching to get the feeling that I had when I was a kid and hearing a Dsus4 resolve to a Dmaj. Now it takes hearing a Cmaj-over-Ab go to Gmaj-over-F#. Six months from now, it may take a cluster resolving to another cluster.
I’m going to keep searching for that feeling, because I think that’s what music is about. It’s about trying to explain the emotional and spiritual condition of human existence.
