新しい複雑性
Like many other works by Ferneyhough and other New Complexity composers, "Etudes Transcendantales" is infamously difficult to perform and is extremely complicated. Pitch-wise, the notes are freely sampled from all 12 tones and the quarter tones in between. Rhythmically, Ferneyhough is known for his nested irregular tuplets, and there is no exception here. Almost each individual note also has its own unique dynamics and articulation, including extended techniques such as multiphonics on the oboe, glottal stops for the voice, and key-clicking for the flute.
