"M3 (MADHAV Lab Mistake Detection for Music Teaching Database)"

"Music pedagogy, particularly in India, is an oral-aural tradition where the teacher sings along with the learner, mostly one-on-one. In the most common setup, teaching proceeds in a call-and-response fashion, where the teacher sings a short piece, and the learner repeats the same. For instance, the teacher may trim the original piece to include only the segment sung incorrectly by the learner. If the mistake persists or corresponds to an essential concept, the teacher may take a detour to a series of lessons aiming at cultivating that particular concept. This work is a step towards emulating this paradigm computationally. The teacher\u2019s lessons are recorded priori. A learner is presented with these lessons, one piece at a time, sequentially. As the learner repeats the piece, her mistakes are to be detected computationally. Detection of singing mistakes is the primary task of this work. This is to be accomplished by comparing the teacher\u2019s audio with that of the learner. The concept of tonic or keynote is very essential in Indian classical music. Generally, this note, often along with some other essential ones, is played throughout the performance via a drone instrument known as tanpura. The pedagogy involves practicing with the drone instrument playing in the background."
