Abstract

While Georgia has a long history of orally transmitted polyphonic singing, there is still an ongoing controversial discussion among ethnomusicologists on the tuning system underlying this type of music. First attempts have been made to analyze tonal properties (e. g., harmonic and melodic intervals) based on fundamental frequency (F0) trajectories. One major challenge in F0-based tonal analysis is introduced by unstable regions in the trajectories due to pitch slides and other frequency fluctuations. In this paper, we describe two approaches for detecting stable regions in frequency trajectories: the first algorithm uses morphological operations inspired by image processing, and the second one is based on suitably defined binary time–frequency masks. To avoid undesired distortions in subsequent analysis steps, both approaches keep the original F0-values unmodified, while only removing F0-values in unstable trajectory regions. We evaluate both approaches against manually annotated stable regions and discuss their potential in the context of interval analysis for traditional three-part Georgian singing.
