Music is a universal language that can express emotions, tell stories, and inspire people. But creating music takes work. It requires talent, skill, and creativity. What if there was a way to generate music with the help of artificial intelligence (AI)?
That’s what Meta, formerly known as Facebook, has done with MusicGen, a generative AI model for producing music based on text prompts or audio samples. MusicGen is a free, open-source tool that anyone can use to create original compositions with the power of AI.
This article will explain what MusicGen is, how it works, and how you can access and use it to make your music.
What is MusicGen?
MusicGen is a generative AI model that can produce music based on natural language prompts or audio samples. For example, you can type “a rock song with electric guitar and drums” or “a lullaby with piano and flute,” and MusicGen will generate a 12-second musical clip that matches your description. You can also provide a short audio clip as a reference for the AI to build on.
MusicGen is built on a Transformer model, as most language models are used today. MusicGen predicts the next segment of a piece of music like a language model predicts the following letters in a phrase. The researchers use Meta’s EnCodec audio tokenizer to break the audio data into smaller pieces.
MusicGen is trained on 20,000 hours of music, about half licensed and high-quality music tracks, and 390,000 instrumental songs curated from stock media libraries Pond5 and Shutterstock. MusicGen can generate music in various genres, styles, moods, and instruments.
MusicGen is not the first of its kind. Google recently unveiled a similar tool of its own called MusicLM. However, while not the first, MusicGen is a little further along than Google’s efforts, with researchers finding MusicGen to best it across several categories.
Researchers compared Meta’s MusicGen with similar software, including Google’s MusicLM, Riffusion, Mousai, and Noise2Music. The study found that objective and subjective measurements saw Noise2Music able to deliver a more “plausible” result. Still, MusicGen scored highest for accurate musical concepts, audio-to-text alignment, and human-scored overall audio quality and accuracy.
How to access MusicGen?
Meta has released MusicGen as an open-source software, allowing anybody to get in on the action and try their hand at generating music with the power of AI. That said, Meta still needs to provide the data it was trained on (which is reported ~20,000 hours of licensed music). However, it has provided pre-trained models at differing parameters of 300 million, 1.5 billion, and 3.3 billion.
You’ll need in-depth know-how and sizable hardware to run this locally on your system, with Meta suggesting a GPU with at least 16GB of RAM. However, you can also demo the software online at Facebook’s HuggingFace space.
To access MusicGen online, you need to visit https://huggingface.co/spaces/facebook/MusicGen. You will see a simple interface to enter your text prompt or upload your audio sample. You can also choose the model size (300M or 1.5B) and the temperature (a parameter that controls the randomness of the generation). Then you can click “Generate” and wait for a few seconds until MusicGen produces your musical clip. You can listen to it online or download it as an MP3 file.
How to use MusicGen?
MusicGen is a fun and easy way to experiment with AI-generated music. You can use it for various purposes, such as:
- Learning about music theory and composition
- Exploring different genres and styles of music
- Creating background music for videos or podcasts
- Generating melodies or harmonies for your songs
- Inspiring your creativity and musical expression
To use MusicGen effectively, you need to follow some guidelines and tips, such as:
- Be specific and clear in your text prompt. Use descriptive words that convey your desired music genre, style, mood, and instruments. For example, instead of “a happy song”, try “a cheerful pop song with upbeat drums and guitar”.
- Use punctuation and capitalization in your text prompt. MusicGen is sensitive to these elements and will use them to structure your music. For example, a comma will create a pause, a period will end a phrase, and a capital letter will start a new phrase.
- Provide a short and relevant audio sample. MusicGen can use an audio sample as a reference to generate similar or complementary music. The audio sample should be less than 12 seconds long and match your text prompt’s genre, style, mood, and instruments.
- Experiment with different model sizes and temperatures. MusicGen offers two model sizes: 300M and 1.5B. The larger model can generate more complex and diverse music, but it may also take longer and produce more errors. The temperature is a parameter that controls the randomness of the generation. A higher temperature will create more dramatic and creative music but may also be less coherent and realistic.
MusicGen is a generative AI model that can produce music based on text prompts or audio samples. It is a free, open-source tool that anyone can access and use online or locally. MusicGen can generate music in various genres, styles, moods, and instruments. It can be used for learning, exploring, creating, or inspiring music.
MusicGen could be better and cannot replace human musicians or composers. It is still a work in progress and may have some limitations and errors. However, it is a remarkable achievement of AI research and a fascinating example of how AI can augment human creativity.
