MusicGen is a free, open-source AI tool developed by a team at Facebook that allows users to generate high-quality, copyright-free music from a single line of text or a bass melody. This tool can be used locally on a computer with a powerful GPU, and does not require as much VRAM as initially stated on the GitHub page. This article will guide you through the prerequisites for installation, instructions for local installation, and instructions for Google Colab installation.

Prerequisites for Installation
Before you begin the installation process, you need to have a few things installed on your computer:
Git
If you haven’t installed it already, it’s very easy. Just download it for Windows and follow the installation process to install it on your computer.
Python
If you haven’t installed Python already, you need to download the Windows installer and follow the installation process. Do not forget to check the box to add Python to your path, otherwise, it’s not going to work.
PyTorch 2.0.1
You need to install PyTorch 2.0.1 with CUDA. If you don’t know how to do this, you can copy the entire line of code provided in the document, look for the command prompt in your startup menu, paste the command, and press enter. You’re going to wait for everything to be uninstalled and then do the same thing with the second line of code. If you don’t have PyTorch 2.0.1 installed, you absolutely need to do this first.
Local Installation Instructions
Once you have installed the prerequisites, follow these steps to install MusicGen locally on your computer:
Create a New Folder
Create a new folder on your computer. You can name it anything you like, for example, “music”.
Open Command Prompt in the New Folder
Once inside the folder, click on the folder path, type CMD, and press enter. This will open the command prompt window.
Clone the Repository
Copy and paste the command line provided here
git clone https://github.com/facebookresearch/audiocraft.git
into the command prompt window and press enter. This will clone the repository onto your computer, creating a new folder.
Download the Requirements
Once inside the new folder, click on the folder path, type CMD, and press enter. Copy and paste this line
pip install -e .
into the command prompt window and press enter. This will download all the requirements needed to run the tool.
Run the Web UI
To run the web UI, simply type python app.py into the command prompt. If you see a Triton error, don’t worry, this is normal and will not impact the quality of the results. You will see a local URL that you can access by holding Ctrl and then left-clicking.
Google Colab Installation Instructions
If you don’t have a powerful GPU, you can still use Music Gen for free using a Google Colab document. Here’s how:
Open the Google Colab Document
Click on the link provided in the document. This will take you to a page where you can open a simple and easy-to-use Google Colab document.
Run the Cell
Click on the cell in the document and then click on “run anyway”. Wait for everything to be installed. This might take a few minutes.
Access the MusicGen UI
Once the installation is complete, you will be given a public URL. Click on it to launch the MusicGen UI, just as if it was running locally on your computer.

Use MusicGen
Once the MusicGen UI is up and running, you can use it in the exact same way as the local version. Just input a text, select a model, and then click on submit. After a few minutes, you will get your generated music. If you want to download the music, do not forget to click on the download icon.
Generating Music with MusicGen
MusicGen allows you to generate music from a single line of text or a base melody. Here’s how:
Input Text or Melody
You can input a line of text or a melody to generate music. If you’re using a melody, you can use one that you’ve downloaded somewhere else or created yourself, and then transform it into a completely different style.
Select a Model
Choose the model you want to use for your music generation.
Submit
Click on submit and wait for your music to be generated. The first time you generate music, it will start downloading the model you chose, which might take a few minutes. But after that, the process will be much faster.
Download Your Music
Once your music is generated, you can listen to it directly on the UI. If you want to download the music, click on the download icon.
MusicGen is an incredible tool for small creators on platforms like YouTube and Twitch, as it allows them to generate copyright-free music in any style they want, saving them from potential copyright claims and helping them monetize their content.
