摘 要：Musical score following has many practical applications. As mobile devices get more popular, musicians would like to carry their sheet music on their mobile devices. One useful functionality that a sheet music app could o er is to have the app follow the music being played by the musician and turn pages at the right time. In this paper, we describe how we combined several techniques to accomplish this task and how we implemented it to run eciently. By understanding basic sheet music semantics and how instruments produce sound, we carefully constructed a hidden Markov model to follow a player's position in a musical score solely by listening to their playing. We implemented our algorithm in Java, in the form of a sheet music application for Android, and it was able to successfully follow amateur-level pianists playing Twinkle Twinkle Little Star, as well as Minuet in G, by J.S. Bach.
