Fig. 1. Representation of a solo flute signal as a collection of harmonic molecules. Each atom is represented by a parallelogram centered at its time-pitch coordinates (u, f 0 ), whose width, height and inclination are respectively proportional to its scal

Fig. 3. Flow chart of the proposed algorithm for the extraction of prominent harmonic molecules.
Fig. 4. Selection of the forward path. The frequency log-variation threshold D is assumed to be equal to the frequency discretization step and the pitch search region is delimited by the two diagonal lines
