who is Arnold Schoenberg?
Schoenberg is a 20th Century composer known for focusing on atonal compositions. Atonal music doesn't adhere to musical conventions such as keys or scales, so the melodies are often very discordant and disharmonious (at least by traditional standards). The resulting music tends to be quite jarring and suspenseful, which can make it useful in movies and games. However, it can also be quite humourous and surprising, or simply an interesting musical experiment.
The reference was due to the fact that you've tweaked the melodies so that they often wander away from the harmonic structure of the chords and sound "out of tune" (which I'm sure has been done in the good name of fun); this happened to remind me of some atonal music I heard during my days as a student
