We assume that the F0 trajectories are generated by a dynamic system and represented in a F0-△F0 phase plane. In this plane, a fluctuation in a sung melody can be modeled by a damped oscillation of the dynamic system and appears as a curling trajectory around a certain target point, i.e., an attractor of the system. The advantage of this modeling is that the location of each attractor corresponds to the F0 of its target musical note and typical singing behaviors can be characterized by the shape of curling trajectories. By using this representation, we also define a melodic similarity measure for query-by-humming (QBH) applications. Our experimental results show that the proposed similarity measure is superior to a conventional dynamic-programming-based method.
