Begin where your
education left off.
Collegiate music theory courses plus interactive practice with instant feedback — for students who need help with their courses, and learners continuing their education.
What you get
Theory I – IV
Diatonic harmony through twentieth-century post-tonal techniques — the full university theory sequence.
Exercises with real feedback
Part-writing, chord-building, interval and chord ID, ear training, and more — each with pitch-level feedback.
Music history
From plainchant through serialism — a survey course designed alongside the theory sequence.
Who it’s for
Working through Theory at university.
Use Continuo alongside your coursework. Practice the chords your textbook just covered — in the same notation your professor uses — then check your work with pitch-level feedback.
Adults coming back to music.
Maybe you majored in performance and never finished theory. Maybe you studied years ago and want to pick it back up. Continuo meets you where you are and takes you further.
