This is a slightly older video of two atonal compositions I composed which embrace complexity, and for their sake are "difficult for the sake of being difficult." Yes, this type of genre indeed exists.
Mathematically, rhythmically, chromatically, atonally, technically, and theoretically these two Atonal Etudes of mine pose separate challenges.
Atonal Etude #1- this piece is rhythmically stable, yet theoretically, chromatically, and atonally difficult to comprehend. Constructed harmonically from only one atonal trailing line, this piece poses extreme difficulties when committing to memory.
Atonal Etude #2- this piece is mathematically, rhythmically, chromatically technically, atonally, and theoretically difficult. So, pretty much difficult for everything. This piece features moments broken down into bare mathematical atonal patterns, which still semi-function as being 'harmonic' with extremely complicated rhythmic content and subdivisions.
The notes are all there.
