Generating Music with Deep Learning

This repository contains all the scripts used in the project Generating Music with Deep Learning. It is divided into two folders:

• midinet. It covers the second part of the project.
• preliminary_work. It includes the preprocessing steps for MAESTRO dataset, as well as the codes for training the LSTM, GAN and VAE models.

In every folder you will find additional information.

Abstract. This paper presents various approaches of music generation based on deep learning techniques. First, after a short introduction to the topic, the article analyses three early proposals: a LSTM, a Variational Autoencoder and a GAN, for symbolic music generation on MIDI, and we gently illustrate the variety of concerns they entail. Second, we leverage the power of a novel architecture called MidiNet by conducting our own refinements, and give examples of how this model, equipped with such a conditional mechanism on melody, can achieve very promising results on music generation.
