Capo

Capo is a music learning and analysis tool designed to help musicians learn songs by ear. It analyzes any song in a user's music library, revealing beats, chords, and key. Instead of relying on curated lessons or prescribed curriculum, Capo allows users to directly interact with their favorite music. The software features pitch and tempo adjustment capabilities, allowing users to slow down music without changing the pitch, facilitating detailed analysis. It supports looping regions of a song, making it easier to focus on specific parts or solos. Capo is available for macOS, iPhone, and iPad, with syncing capabilities between devices. It's used by both beginner and professional musicians for transcribing, learning new songs, and developing original music.
