The music I've always been drawn to as a listener is improvisational music. There is some improvisation - AKA "self expression" - to be found in Irish music, but traditionally it stays within a fairly confined melodic structure. The kind of improv I'm talking about is of a more open, unstructured variety.
The on-demand commercialized way we hear and consume music - on our smart phones, on Spotify, in a TV show, or movie or advertisement - is a recent phenomenon. The music that makes it to the top of these queues is the stuff that's the easiest to digest; dumbed down to a point of easy comprehension for those needing to be impressed and entertained.
It used to be that the only music anyone ever heard was made live on the spot. I want to get back to that earlier connection, that closeness, that people had with music. And when you think about it , improvised music had to have been the first type of music. It wasn't analyzed or codified until long after it was created.
Improvised music is free -- free of the restrictions of style, idiom or prescription. Anyone can do it without even thinking about it, but I kinda want to study it, which is why I might start taking some lessons on improvisation.
In the meantime, bang on a can / pluck a string. See what notes and tones want to be heard today.
