{"url":"/dataset/pop909","name":"POP909","full_name":"POP909","description_markdown":"**POP909** is a dataset which contains multiple versions of the piano arrangements of 909 popular songs created by professional musicians. The main body of the dataset contains the vocal melody, the lead instrument melody, and the piano accompaniment for each song in MIDI format, which are aligned to the original audio files. Furthermore, annotations are provided of tempo, beat, key, and chords, where the tempo curves are hand-labelled and others are done by MIR algorithms.\r\n\r\nSource: [https://arxiv.org/pdf/2008.07142.pdf](https://arxiv.org/pdf/2008.07142.pdf)\r\nImage Source: [https://arxiv.org/pdf/2008.07142.pdf](https://arxiv.org/pdf/2008.07142.pdf)","description_withheld":null,"homepage":"https://github.com/music-x-lab/POP909-Dataset","introduced_date":null,"introduced_date_note":null,"introduced_by":{"paper":"/paper/pop909-a-pop-song-dataset-for-music","title":"POP909: A Pop-song Dataset for Music Arrangement Generation","first_author":"Ziyu Wang","url":null},"license":null,"modalities":[{"name":"Audio","url":"/datasets/modality/audio"}],"tasks":[{"name":"Style Transfer","url":"/task/style-transfer","datasets_with_task":"/datasets/task/style-transfer"},{"name":"Music Generation","url":"/task/music-generation","datasets_with_task":"/datasets/task/music-generation"}],"languages":[],"variants":["POP909"],"data_loaders":[{"repo":"https://github.com/music-x-lab/POP909-Dataset","url":"https://github.com/music-x-lab/POP909-Dataset","frameworks":["tf"]}],"num_papers_in_archive":43,"source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28"},"benchmarks":[],"papers_with_a_benchmark_row":[],"syntology_totals":{"read_at":"2026-09-25T09:33:49+00:00","papers_with_samples":0,"samples_harvested":0,"samples_ran":0,"samples_unverified":0,"pointer_only_for_licence":0,"papers_with_no_sample_that_ran":0,"note":"the per-paper counts above, summed; not a rate"},"papers_note":"The archive never published its papers-using-dataset list; these are papers with a leaderboard row on this dataset's benchmarks."}
