This melody is simple and echoed by all instruments in the ensemble, with the French horn playing every second note of the melody, the violin playing every fourth note, viola playing every eighth, and so on. The melody has been constructed to be self-similar. Consequently, the process for each of these resultant parts generates the same melody, but one that is shorter. When played together, this produces emergent harmonies, and an accompaniment that lasts an equivalent fraction of the whole duration. The duration of the individual notes are therefore lengthened to compensate.
