Hands-On Music Generation with Magenta

By: Alexandre DuBreuil

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.

Chapter 6: Data Preparation for Training

  1. MIDI is not a text format, so it is harder to use and modify, but it is extremely common. MusicXML is rather rare and cumbersome but has the advantage of being in text format. ABCNotation is also rather rare, but has the advantage of being in text format and closer to sheet music.
  2. Use the code from chapter_06_example_08.py, and change the program=43 in the extraction.
  3. There are 1,116 rock songs in LMD and 3,138 songs for jazz, blues, and country. Refer to chapter_06_example_02.py and chapter_06_example_03.py to see how to make statistics with genre information.
  4. Use the RepeatSequence class in melody_rnn_pipeline_example.py.
  5. Use the code from chapter_06_example_09.py. Yes, we can train a quantized model with it since the data preparation pipeline quantizes the input.
  6. For small datasets, data augmentation plays an essential role in creating...
