Hookpad Aria: A Copilot for Songwriters
This is an incremental tool for songwriters to enhance non-sequential composition workflows.
The paper tackles the problem of assisting musicians in writing Western pop songs by introducing Hookpad Aria, a generative AI system integrated into a web-based editor, which has generated 318k suggestions for 3k users with 74k accepted into songs since its release.
We present Hookpad Aria, a generative AI system designed to assist musicians in writing Western pop songs. Our system is seamlessly integrated into Hookpad, a web-based editor designed for the composition of lead sheets: symbolic music scores that describe melody and harmony. Hookpad Aria has numerous generation capabilities designed to assist users in non-sequential composition workflows, including: (1) generating left-to-right continuations of existing material, (2) filling in missing spans in the middle of existing material, and (3) generating harmony from melody and vice versa. Hookpad Aria is also a scalable data flywheel for music co-creation -- since its release in March 2024, Aria has generated 318k suggestions for 3k users who have accepted 74k into their songs.
