Oh my good gracious
Do you really think I could read this, let alone play it?
But feel free to post a performance by yourself 
I'm having trouble with bar 1. What fingers should I use? How should I voice the notes?

I'm gonna play it on my kazoo, afterall, it's for piano or "any other instrument"...

now that's the spirit.
!!! "Forehead" LMAO!!!
I thought about the nose, but I woudn't want to be responsible for broken noses in the event someone feels they need a spirited sforzando.
Wow. I really don't get it. You're a nice guy quantum so I wouldn't dream of ranting and raving like I do about xenakis, but...I just don't get it lol. It's actually funny to look at something like that (what with fists and foreheads etc.). No offense intended at all. I've heard many of your improvs and found them really cool (especially some of the meditation ones). But...you've definitely got that "eccentric" thing down pat!
Well actually humor was very much intended when I wrote this. I was feeling in a bit of a silly mood. Those of us who may have had to perform some eccentric music in uni as part of an exam may relate more to it. I used to stay far away from such eccentric music, but over the years have grown to appreciate it.
A bunch of silly situations, blown totally out of control. There's a part of me that wanted to make at least some of it plausible, and the other part of me that said go to town and have fun. I've seen other composers write a dynamic for almost every note in a bar, so why not do that for every rest too; nested dynamics that utterly contradict eachother; crazy polyrhythms, etc. But, I also put some thought into performance choreography, I mean the forehead smashes in the middle of the keyboard is somewhat possible with both hands playing at the extreme.
Some parts of it are there because I thought it looked pretty in the score

Actually there are some new things that came out of writing this that I have never tried, but would like to. For example contrary motion glissandi in one hand, elbow glissandi while playing other notes with the hand.
Music can get very academic, especially in a uni setting where you have to be able to write about stuff you may not even understand. I think we all need a bit of stress relief every once in a while and a good laugh.
...but if your willing to put on a serious performance of this, go right ahead. I wonder how it would sound on banjo....Thal?
