The Pop-K MIDI Dataset is an open collection of modern pop melodies developed for training and testing symbolic music models in a constrained musical domain. The dataset contains 305,815 files augmented from a base dataset of 8-bar vocal lead, chords, and bass melody tracks. An accompanying model trained on this dataset can be found on GitHub.
The dataset was created to evaluate how limited training data can be scaled via augmentation to efficiently train a model to generate a specific musical style. Additionally, the melodies were transposed to C major and A minor, with timing information normalized to 120 BPM at a 96-tick resolution. This results in a total duration of approximately 1360 hours of musical notation.
