Mobile

The first version of Mobile for oboe and harp was composed by Heinz Holliger as early as 1962 while studying with Pierre Boulez. The piece is based on the tone row used by Boulez in his Piano Sonata No. 3. Whereas the sequence of the 12 sections was notated aleatorically in the first edition, the practical new edition contains three possible versions of Mobile in a clearly legible computer notation which can be played separately or in free succession.
Instrumentation:
oboe and harp
