The DALI dataset is a large dataset of time-aligned symbolic vocal melody notations (notes) and lyrics at four levels of granularity. DALI contains 5358 songs in its first version and 7756 for the second one. In this article, we present the dataset, explain the developed tools to work the data and detail the approach used to build it. Our method is motivated by active learning and the teacher-student paradigm. We establish a loop whereby dataset creation and model learning interact, benefiting

This process creates an improved DALI dataset after each iteration. Finally, we outline the errors still present in the dataset and propose solutions to global issues. We believe that DALI can encourage other researchers to explore the interaction between model learning and dataset creation, rather than regarding them as independent tasks.
