Départ is a piece for solo piano that focuses on the idea of permutation from one spectrum to another. The two spectra I chose for this piece consist of the natural spectrum of B0 and a stretched spectrum of A1. The piece consists of two layers of pitch material that share motivic ideas. One layer is fixed on the B0 spectrum, while the other layer travels from the static spectrum to the distorted spectrum of A1. The piece ends with both of the spectra played at the same time to finalize the sense of shifting within the piece.
