My approach, so far, to making music is to take conventional jazz standards, deconstruct them, given them a new name and just improvise over the deconstruction. For me, musical deconstruction is tearing the song (chords and melody) apart and reassembling it in some other, updated form. For example, the jazz standard Our Love is Here to Stay becomes Fascism is Here to Stay.
Sebastiene Ammann points out that this type of improvisation is a form of resistance. Here's what I think he is saying. If you are a musician trying to become part of the current Music System (Rock, Pop, Jazz, Classical, whatever) you are involved in a very rigid even authoritarian endeavor. Even Jazz has become Academic and Classical with rigidly proscribed forms (Play the Head, Improvise, Play the Head, Out). If this is what you want to do, Great! I'm not criticizing** just saying that you are part of the System (just try playing like Eric Dolphy in your High School Jazz band, even though Dolphy is an established Jazz musician).
Let's also point out that The System is what brought us the Neo-Fascist Trump 2 Administration. Being part of it makes you complicit and Complicity is Painless. A more painful route is to Deconstruct and Resist. Can You Dig It CUDI?
