A study of variability in raga motifs in performance contexts
An interesting aspect of Indian art music is the prominent place of improvisation in performance. We explore the influence of the structural constraints of the genre on raga motifs in the course of improvisation. Audio recordings of North Indian vocal concerts are analysed to extract measurements of the defining parameters of the recurrent melodic phrases that characterise the raga in performance. While improvisation relates to choosing the sequence of phrases at the larger time scales, we show that the categorical nature of the musical melodies is preserved through the interaction of the phrases with the changing melodic and rhythmic contexts.
期刊介绍：
The Journal of New Music Research (JNMR) publishes material which increases our understanding of music and musical processes by systematic, scientific and technological means. Research published in the journal is innovative, empirically grounded and often, but not exclusively, uses quantitative methods. Articles are both musically relevant and scientifically rigorous, giving full technical details. No bounds are placed on the music or musical behaviours at issue: popular music, music of diverse cultures and the canon of western classical music are all within the Journal’s scope. Articles deal with theory, analysis, composition, performance, uses of music, instruments and other music technologies. The Journal was founded in 1972 with the original title Interface to reflect its interdisciplinary nature, drawing on musicology (including music theory), computer science, psychology, acoustics, philosophy, and other disciplines.
