Abstract

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.

raga基序在表演语境中的变异性研究

印度艺术音乐的一个有趣的方面是即兴演奏在表演中的突出地位。在即兴创作的过程中，我们探讨了流派的结构约束对raga主题的影响。对北印度声乐音乐会的录音进行了分析，以提取表演中raga特征的重复旋律短语的定义参数的测量值。虽然即兴创作涉及在更大的时间尺度上选择短语序列，但我们表明，通过短语与不断变化的旋律和节奏背景的相互作用，音乐旋律的分类性质得以保留。

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.
