Overview of this book

The importance of machine learning (ML) in art is growing at a rapid pace due to recent advancements in the field, and Magenta is at the forefront of this innovation. With this book, you’ll follow a hands-on approach to using ML models for music generation, learning how to integrate them into an existing music production workflow. Complete with practical examples and explanations of the theoretical background required to understand the underlying technologies, this book is the perfect starting point to begin exploring music generation. The book will help you learn how to use the models in Magenta for generating percussion sequences, monophonic and polyphonic melodies in MIDI, and instrument sounds in raw audio. Through practical examples and in-depth explanations, you’ll understand ML models such as RNNs, VAEs, and GANs. Using this knowledge, you’ll create and train your own models for advanced music generation use cases, along with preparing new datasets. Finally, you’ll get to grips with integrating Magenta with other technologies, such as digital audio workstations (DAWs), and using Magenta.js to distribute music generation apps in the browser. By the end of this book, you'll be well-versed with Magenta and have developed the skills you need to use ML models for music generation in your own style.

In this chapter, we'll use the following tools:

The command line or bash to launch Magenta from the Terminal
Python and its libraries to write music generation code using Magenta
Magenta to generate music in MIDI
MuseScore or FluidSynth to listen to the generated MIDI

In Magenta, we'll make the use of the Drums RNN model. We'll be explaining this model in depth, but if you feel like you need more information, the model's README in Magenta's source code (github.com/tensorflow/magenta/tree/master/magenta/models/drums_rnn) is a good place to start. You can also take a look at Magenta's code on GitHub, which is well documented. We also provide additional content in the last section, Further reading.

The code for this chapter is in this book's GitHub repository in the Chapter02 folder, located at github.com/PacktPublishing...
