Furthermore, the syntax doesn't feel "readable" like a music score. The symbolic notation doesn't click for me. I'd like to be able to hear what is going on in my head, and this just doesn't seem designed for that. By contrast, Alda (a musical language posted yesterday) is very readable to me as a musician. ABC notation and Lilypond were very good sources of inspiration.
There are some things I like about Skoar. The use of a really good audio engine to produce the sound wins in my book (there doesn't seem to be any obvious way to control the sound itself, though.) I think the way you express dynamics using hashes is pretty novel. (May want to consider using decibel scaling instead of linear scaling.) I like the fact that you have incorporated programming elements like conditionals, loops, and variables.
Both Alda and Skoar basically focus on conventional western music notation, which is perhaps the most boring part of computer generated music. Sound design plays much greater importance, and it makes me sad to see no focus on that whatsoever (Sound is uh... the part that actually makes the music).
I'm hesitant to share this on HN because it's not done yet, but I too, made yet another musical language:

Here's the code:

And here's what it can sound like (everything minus the outdoor ambient sample is synthesized in Sporth):
