This article proposes a method for transcribing a piano note that is overlapped by previous notes. It is suggested that by referring to a short context before the note being transcribed, it is possible to improve the performance of a note transcriber by removing the contribution of previous notes. This removal can be performed either explicitly to produce a novelty signal, or implicitly inside the note transcriber, with the latter leaving a space for further optimization. Experiments show that the method dramatically improves the performance of a simple transcriber.
