To the average listener, Stravinsky's works like the Firebird may sound atonal, but it is not. I'm aware of bi-tonality and modes and such, but Stravinsky doesn't seem to stick to one specific scale. He's known for his petrushka chord/scale and is known to have used the octatonic scale and other types of these things, but I'm composing a work with no tonal home for university (can't be strictly atonal) and I just can't quite figure out how one goes about doing this.

I know his music is not just random sounds, but I can't put my finger on exactly what's going on.
