Songsmith is a system that automatically chooses chords to accompany a vocal melody. A user with no musical experience can create a song with instrumental accompaniment just by singing into a microphone, and can experiment with different styles and chord patterns using interactions designed to be intuitive to non-musicians. Our goal is to let people with no training in chords or harmonization get a taste of songwriting.
Songsmith uses a Hidden Markov Model (HMM) to optimize the chord sequence for a new melody, and we’ve trained our HMM on a database of popular music lead sheets. In this talk, I’ll describe how Songsmith works, I’ll discuss how we let users interact directly with our HMM without requiring a degree in computer science, and I’ll show lots of audio examples to demonstrate that non-musicians are in fact able to use this system as a powerful creative tool.
Warning: singing during this talk is inevitable. Bring your enthusiastic singing voices or you’ll quickly get tired of hearing me sing.
