Figure 8
GMM with 13 Gaussians fitted to pitch histogram determined from adapted F0-trajectories of the song “Gushin Shentana” (GCH-ID 010). The black numbers on top of the peaks indicate the peak values in cents, while the red numbers indicate the intervals between neighboring peaks. The original distribution is indicated in grey color.
