Jukebox is designed to generate music from scratch, given specific inputs such as genre, artist, and lyrics. Provided with genre, artist, and lyrics as input, Jukebox outputs a new music sample produced from scratch. This allows for a wide range of musical styles and genres to be explored and created.

Rudimentary Singing

While Jukebox can produce music, it also has the capability to generate rudimentary singing. Note that Jukebox doesn’t generate lyrics: it can only sing lyrics when they’re provided as input. Without lyrics for guidance, Jukebox generates nonsensical vocal utterances in the style of the original singer.

Genre and Artist Style Imitation

Jukebox can imitate the style of specific genres and artists. This is achieved through a high-level transformer model trained to estimate squeezed audio tokens, allowing Jukebox to capture the essence of any music style. This feature enables the creation of music that closely resembles the work of well-known artists and genres.

The resulting work is a clear leap forward in musical quality, though it comes with some limitations.

Training Data and Methodology

Dataset Composition

To train the model, the team crawled the web to curate a new dataset of 1.2 million songs, 600,000 of them in English, paired with corresponding lyrics and metadata. The metadata included genre, artist, and year of the songs. To increase the size of the dataset, the team performed data augmentation by randomly downmixing the right and left channels to produce mono audio.

Metadata Utilization

The metadata played a crucial role in the training process. By incorporating information such as genre, artist, and year, the model could better understand and generate music in various styles. This enriched the model’s ability to produce more accurate and contextually relevant outputs.

Training Techniques

  1. The VQ-VAE that involved around 2 million variables, was trained on 256 Nvidia V100 graphics cards for three days.
  2. The upsamplers that consisted of more than 1 billion variables, were trained on 128 Nvidia V100 graphics cards for two weeks.
  3. The top-level prior that carried across 5 billion variables, was trained on 512 Nvidia V100 graphics cards for four weeks.

Training Jukebox required substantial computational resources and time, highlighting the complexity and scale of the project.

Exploring Generated Samples

Sample Exploration Tool

OpenAI’s Jukebox provides a fascinating sample exploration tool that allows users to delve into a vast library of generated music. Even with those limitations, the results are just incredible to explore. I recommend starting with the featured samples from the blog post, and then diving into the uncurated library of over 7,100 song samples.

Guided vs. Unguided Generation

The tool offers both guided and unguided generation options. Guided generation allows users to specify certain parameters, such as genre or artist style, while unguided generation lets the model create music freely. Just digging around the sample library, I found so many intriguing examples. It’s the uncanny valley of music: machine-hallucinated melodies and nonsensical DeepDream-esque vocals, but often capturing the style and mannerisms of the artist it’s trying to mimic.

Quality of Generated Music

The quality of the generated music can vary. While some samples are impressively close to the style of well-known artists, others may sound more experimental. Unfortunately, making your own songs won’t be as easy. While the code is available, OpenAI says it takes three hours to render 20 seconds of audio on an NVIDIA Tesla V100, a $10,000 GPU. You can experiment with it on Google Colab for short, low-quality samples, but rendering times and memory limits may make it challenging.
