MAESTRO-E

MAESTRO-E dataset for music practice error detection with paired performance/reference inputs and note-level error labels.

Paired Inputs for Error Detection

The model takes paired inputs:

mistake: performance audio/MIDI containing musical errors
score: paired reference score audio/MIDI (target/correct context)

Error supervision is provided with labels:

label/extra_notes
label/removed_notes
label/correct_notes

Full Structure (Code-Compatible)

This repo preserves the filesystem layout expected by the training loader:

mistake/<sample_id>/...
score/<sample_id>/...
label/{extra_notes,removed_notes,correct_notes}/<sample_id>/...
maestro-v3.0.0.json (included at repo root)

Quick Start (Directly with Existing Code)

from huggingface_hub import snapshot_download

root = snapshot_download("ben2002chou/maestro-e", repo_type="dataset")
# set root_dir = root
# set split_json_path = f"{root}/maestro-v3.0.0.json"
