SB 1.0 — The First Dynamic Database for Musical Stream Physics (Turkish A Cappella, Makam USSAK)

SB 1.0 is the first dynamic and computationally-driven dataset for Musical Stream Physics (Karmil Streams). It provides section-based a cappella audio (Zemin, Nakarat, Meyan) from the Turkish Makam song “Aksam” performed by Safiye. Makam is confirmed as USSAK. Form: Şarkı. Usul: Düyek. The dataset includes word-level Praat TextGrid annotations and full Stream Physics parameterization: φ(t), |Δφ−π|(t), E_str(t), ψ(t), and K_eq(t). These features enable quantitative research on phase coherence, musical energy balance, and stream directionality in monophonic performance. SB 1.0 aims to establish a foundational benchmark for evaluating musical flow dynamics across cultures and repertoires. It is fully reproducible and licensed under CC BY 4.0. Data derived from “Turkish Makam A Cappella Sections Dataset v1.0” (Original DOI: 10.5281/zenodo.1283356), with new computed layers and curated metadata. This release includes:• AUDIO & TextGrid alignment• Stream Physics time-series (CSV)• Manifest and metadata• Visual analytical report (PDF) SB is the core dataset for the scientific development of Karmil Streams.
