The series of works collectively titled Redundens was begun in 2001. All the pieces take Arnold Schoenberg’s Three Pieces for Piano, Op.11 as their starting point: only the top line in Schoenberg's pieces is retained as an unaccompanied melody (or as a list of pitch classes if you’re more technically-minded.) Each set of pieces uses a different method of encoding this melody; by pitch, register, timbre, duration, dynamics, or other means.
In Redundens 1 each pitch class keeps the same register and duration throughout the piece, determined by the nature of their initial appearances in the original. Redundens 1b is Redundens 1 for solo piano.
