In this paper, we present an approach to transcription of varnams in Carnatic music using hidden Markov models (HMMs). We draw upon domain-specific information in that we build rāga-specific HMMs and use rhythmic cycle (tā⋖a) information in the initialization of the HMMs and in the postprocessing of the output. The ground truth is obtained from standard notations of varnams. Transcription performance...
In this work, we explore the task of musical onset detection in Carnatic music by choosing five major percussion instruments: the mridangam, ghatam, kanjira, morsing and thavil. We explore the musical characteristics of the strokes for each of the above instruments, motivating the challenge in designing an onset detection algorithm. We propose a non-model based algorithm using the minimum-phase group...
