The document proposes a partnership between Spotify and Riffstation to build a music learning tool called "Spotify Chords" that displays chord charts for songs on Spotify. It notes that current practice tools are lacking and that musicians want resources that are organized, mobile-optimized, interactive, and high-quality. Spotify Chords would allow users to watch chord charts scroll on screen, choose instruments, and customize their playing experience. The document estimates there could be millions of potential users and argues the product would be beneficial for both companies.
