Articulations Included

Performers

Captured with expert musicians and vocalists across global traditions — ensuring each dataset carries authentic nuance, human expression, and rights-managed provenance.

Audio Demonstrations

A three-part listening benchmark: a mixed musical demo built from this dataset, the raw source clip, and an AI model’s attempt to reproduce the same prompt.

PRODUCED REFERENCE

A musical demonstration created by replacing a state-of-the-art AI-generated lead instrument with original source recordings from this dataset, then arranged and mastered to preserve musical context. This approach allows direct comparison between current-generation model output and real, rights-cleared acoustic source material.

RAW DATASET CLIP

Directly from the dataset: an isolated, unprocessed example of the source recording.

AI MODEL BENCHMARK

An unmodified output from a current-gen AI model given the same musical prompt. Included to illustrate where today’s systems still differ from real, recorded sources.

AI model approximations generated using publicly available state-of-the-art music generation systems.
