How MusicGen Works
MusicGen operates by leveraging a cutting-edge AI model trained on an extensive dataset of licensed music. The training process involved analyzing a vast collection of 20,000 hours of high-quality music tracks, including Meta’s internal dataset as well as tracks sourced from Shutterstock and Pond5. This diverse corpus of musical styles and genres empowers MusicGen to offer a wide range of creative possibilities.
To optimize performance, Meta employed their 32Khz EnCodec audio tokenizer, which breaks down the music into smaller chunks. This enables parallel processing, resulting in faster and more efficient music generation. Users can input various text prompts, such as a specific genre or melody, to guide MusicGen in producing a composition that aligns with their desired musical direction.
Furthermore, MusicGen allows users to provide a reference audio file, which serves as a blueprint for generating new music. By aligning the generated composition with the reference track, MusicGen offers a unique opportunity to create harmonious pieces that resonate with established melodies or songs.
What Are MusicGen’s Features
- Music Generation Based on Text Prompts: MusicGen harnesses the power of AI to create original music compositions based on text prompts provided by the user. From specifying a genre to outlining a melody, users can explore an array of creative possibilities.
- Training on Extensive Music Dataset: The AI model driving MusicGen was trained on a vast collection of licensed music, comprising 10,000 high-quality tracks from Meta’s internal dataset, as well as tracks sourced from Shutterstock and Pond5. This diverse training dataset ensures that MusicGen can cater to a wide range of musical styles and genres.
- Quick and Easy Music Creation: MusicGen simplifies the process of generating new music by providing a user-friendly interface and intuitive controls. Musicians and producers can swiftly experiment with different ideas and concepts, expediting their creative workflow.
- Facilitates Creative Experimentation: With MusicGen, artists can push the boundaries of their creativity by experimenting with new musical ideas. By providing a platform for exploration, MusicGen encourages the discovery of novel melodies, harmonies, and rhythms.

Meta’s MusicGen vs Google’s MusicLM
Google too launched its own text to music generator MusicLM at Google I/O 2023 so let’s compare these products:
| Feature | MusicGen | MusicLM |
| Model type | Single-stage (Music generation all at once) | Hierarchical (Music generation in parts) |
| Training data | Music scores | Audio recordings |
| Availability | Open source | Not open source |
| Strengths | Quick and easy to use, can generate music in a variety of styles | High-quality music that sounds like real-world recordings |
| Weaknesses | Can be less accurate than MusicLM, may not be able to generate music in all styles | Limited to Google employees and select partners. |
Benefits of MusicGen
Here are some specific examples of how MusicGen can be used to benefit musicians and music producers:
- A beginner musician can use MusicGen to learn about different musical styles and techniques. They can experiment with different prompts and see how MusicGen generates different results. This can help them to develop their own musical style and to learn new techniques.
- An experienced musician can use MusicGen to experiment with different melodies, rhythms, and harmonies. This can help them to come up with new ideas for songs that they would not have thought of on their own.
- A music producer can use MusicGen to generate different styles of backing tracks, which can be used to create a variety of different moods and atmospheres.
Limitations of MusicGen
Variable Output Quality: While MusicGen endeavors to generate high-quality music, the AI system’s output may not always meet users’ expectations. Due to the complex nature of music composition and individual preferences, some generated pieces may fall short in terms of perceived quality.
As Meta open-sources MusicGen to create music from text prompts, it signifies a significant milestone in the realm of generative AI tools for music creation. As musicians and producers increasingly embrace AI-driven technologies, MusicGen offers a promising avenue for exploration and innovation.
