Signal Dat — Musicology Annotations Sample

50-track sample from the Signal Dat dataset: human-annotated musicology records for training generative audio AI, music recommendation, and MIR models.

Full dataset (710+ tracks) available at signaldat.com

What makes this different

Most audio datasets provide algorithm-extracted features (BPM, key, MFCC). Signal Dat provides human expert annotations — a trained musicologist listens to each track and documents what a machine cannot:

Section-by-section narrative descriptions (4-plane: foreground/midground/background/dynamics)
Melodic contour analysis (conjunct, disjunct, undulating, ascending arch, etc.)
Instrument roles and interplay, not just presence
Vibe and emotional tags grounded in musical context
Production and mix characteristics (stereo field, effects, fidelity)
Global genre/era/scene with cultural context

Every record passes QA before export: no cross-section references, complete instrument lists, and mandatory production assessment.
