We describe the results of the first large-scale raag recognition experiment. Raags are the central structure of In-dian classical music, each consisting of a unique set of complex melodic gestures. We construct a system to recognize raags based on pitch-class distributions (PCDs) and pitch-class dyad distributions (PCDDs) calculated directly from the audio(More)
The paper describes an interactive musical system that utilizes a genetic algorithm in an effort to create inspiring collaborations between human musicians and an improvisatory robotic xylophone player. The robot is designed to respond to human input in an acoustic and visual manner, evolving a human-generated phrase population based on a similarity driven(More)
We describe Tabla Gyan, a system capable of improvising tabla solo music, a sophisticated percussion tradition from North India. The system is based on a generative model of the qaida, a central form in tabla solo based on thematic variation. The system uses a recombi-native process of variation generation, and filters the results according to rhythmic and(More)
A survey of emotion in North Indian classical music was undertaken to determine the type and consistency of emotional responses to raag. Participants listened to five one-minute raag excerpts and recorded their emotional responses after each. They were asked to describe the emotions each excerpt evoked and then to adjust six different sliders indicating the(More)
We describe a series of experiments that attempt to create a content-based similarity model suitable for making recommendations about North Indian classical music (NICM). We introduce a dataset (nicm2008) consisting of 897 tracks of NICM along with substantial ground-truth annotations, including artist, predominant instrument, tonic pitch, raag, and parent(More)
Thiomicrospira(Tms) species are small sulfur-oxidizing chemolithoautotrophic members of the Gammaproteobacteria. Whilst the type species Tms. pelophila and closely related Tms. thyasirae exhibit canonical spiral morphology under sub-optimal growth conditions, most species are vibrios or rods. The 16S rRNA gene diversity is vast, with identities as low as(More)
