MuseNet is a deep neural network model capable of generating 4-minute musical pieces using 10 different instruments. It can blend various musical styles, ranging from country to Mozart and even the Beatles. MuseNet learns and predicts the patterns of harmony, rhythm, and style by analyzing hundreds of thousands of MIDI files, anticipating the next note in each sequence. The model employs the same general unsupervised learning technique used in GPT-2, which predicts the next token in an audio or text sequence.
