Introduction Music genres allow the categorization of music into broad groups of related songs for use in applications such as song recommender systems based on genre. Many existing songs are unlabeled, and new songs are constantly being released. While hand-labeling them all would be too tedious, classifying them by genre can fit them into categories for use in recommendation. Also, even if th...

Music information retrieval has emerged as a mainstream research area in the past two decades. Experiments on music mood classification have been performed mainly on Western music based on audio, lyrics and a combination of both. Unfortunately, due to the scarcity of digitalized resources, Indian music fares poorly in music mood retrieval research. In this paper, we identified the mood taxonomy...

Elucidating the relationship between genetic and cultural evolution is important in understanding speciation, as learned premating barriers might be involved in maintaining species differences. Here, we test this relationship by examining a widely recognized premating barrier, bird song, in a hybrid zone between black-throated green (Setophaga virens) and Townsend's warblers (S. townsendi). We ...

In cities, trees are seen predominantly as entities that beautify streets, parks and gardens. Often they’re regarded obstacles to urban development, where their importance ecosystem health plays a secondary role economic growth. How can multispecies art offer new perspectives on crucial contributions life? Branching Songs is project with old in the Vancouver area, including ‘1308 Trees’, forest...

In this paper some of the prevailing classifications of Indian songs are quantified by measuring their fractal dimension. Samples were collected from three categories: Classical, Semiclassical, and Light. After appropriate processing, the samples were converted into time series datasets and their fractal dimension was computed. Based on these results, an online method for classification is offe...

Songbirds are an excellent model for investigating the perception of learned complex acoustic communication signals. Male European starlings (Sturnus vulgaris) sing throughout the year distinct types of song that bear either social or individual information. Although the relative importance of social and individual information changes seasonally, evidence of functional seasonal changes in neura...

Bird songs are acoustic communication signals primarily used in male-male aggression and in male-female attraction. These are often monotonous patterns composed of a few phrases, yet some birds have extremely complex songs with a large phrase repertoire, organized in non-random fashion with discernible patterns. Since structure is typically associated with function, the structures of complex bi...
