MuseNet is a deep neural network that can generate musical compositions with up to 10 different instruments. It was created using unsupervised learning, where the model discovered patterns of harmony and style by analyzing hundreds of thousands of MIDI files. Unlike traditional music composition methods, MuseNet doesn't rely on explicit programming or human understanding of music theory. Instead, it uses a general-purpose transformer model similar to GPT-2, which is also used for text prediction. --- Why it matters: MuseNet's ability to generate musical compositions with diverse styles and instruments has implications for the field of AI-generated music, where researchers are exploring new ways to create original and engaging content. This technology could potentially be used in various applications, such as film scoring or video game soundtracks. Source: https://openai.com/index/musenet
