What is Reddit's opinion of "Maximum Clarity" and Other Writings on Music?

From 3.5 billion Reddit comments

Well... if you find that, let me know.

No one really teaches how to write in a super contemporary style (ie; one that's happening right now) because it's so new. Spectralism still has a foothold in some places with composers like Haas. He just recently had a piece premiered for 6 microtonally tuned pianos (each tuned a 1/12th tone off [no, the difference is not audibly noticeable]) and orchestra. "Limited Approximations".

Microtonality is an idea that's been around for a bit and is still slowly growing, and you maybe be able to find a book about it, though actually hearing the microtones is a completely different undertaking.

Some microtonal pieces,

Wyschnegradsky Prelude No. 5

La Monte Young The Well-Tuned Piano

Ben Johnston String Quartet No. 10

Ben Johnston String Quartet No. 4

I found a book by Ben Johnston, it may interest you.

Other styles of music that are still popular are minimalism, Arvo Part.

Neo-Romanticism is kindof a thing. David Del Tredici, Christopher Rouse, and Penderecki has stopped writing music in the vain of "Threnody" (much to the dismay of many modernists).

Micropolyphony is an idea famously used by Ligeti , it's basically a lot of the same line happening at different times.

And then there's graphic notation (Morton Feldman and others) and Neo-Complexity (Ferneyhough).

All in all... there's a lot of newer styles of music, but everyone is figuring things out in their own way. And that's pretty much what a composition teacher will want you to do. If you went out and studied with Boulez, he's not going to teach you how to write like Boulez. This has been a rather frustrating thing for myself as a composition student because my teacher (Andy Vores) hasn't been teaching me how to write anything in a different style. He just shows me how to do what I'm already doing better.

If you really want to hear NEW MUSIC, look up the teachers at Universities/Conservatories. Most of the teacher's will have websites and some (like mine above) will have pieces that you can listen to.
