Individual notes are assigned to exactly one auditory stream, altering perceived rhythm.

Evidence

Following the principle of belongingness, each note is organized into one of the competing auditory streams (or it can be perceived as a separate stream), but no note is part of more than one streams. Depending on the case, in Figure 11.17 the final note (F) may be organized either into the upper or lower auditory stream. This also changes the perceived rhythmic pattern accordingly. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 1336
