I’d argue that in recent decades, we’ve seen the rise of electronic music. Things like the MalletStation/MalletKat, Electronic Drumsets, Electric Guitars, Synthesizers, and such have come since then. The electronic Wind Controllers are also pretty cool.

To be honest, the one thing that’s probably the future that we shouldn’t discount is the ability generate music with AI. Back in the 1900s, pianos became incredibly common in households and were the way the common man could make music. Guitars, harmonicas, etc. We draw far more of a line, I feel, to symphony orchestras in our staidness.

If you want to look at the future, you have to put some thought into the ‘Modern Band’ movement that many have begun pushing into. It’s definitely a descendant of the stage bands/jazz bands in my mind.
