El Bongosero Dataset

A Crowd-Sourced Symbolic Dataset of Improvised Hand Percussion Rhythms Paired with Drum


This site is dedicated to the ANON Dataset, a crowd-sourced expressive symbolic dataset consisting of 6,035 improvised tapped sequences performed by 3,184 participants with varying levels of musical expertise.

Each sample contains expressive timing and dynamics information and is annotated with the participant’s self-reported level of musical expertise, the genre of the selected pattern, the chosen tempo, the total duration to complete the activity, and a user-rating for their performance and how much they enjoyed the exhibit.
