Soundscape composition analysis combined with acoustics and musicology: a case study on the music piece of Daybreaking

With its own unique musical vocabulary, soundscape composition has been unprecedently developed all over the world. The analysis of music pieces from the perspective of acoustics has its own advantages that cannot be replaced by the traditional musicology. Based on a music piece named Daybreaking for a hope to overcome COVID-19, this paper analyzes the acoustic elements of SPL, frequency spectrum and waveform. Combined with the traditional musicology, it can show that the undulation of waveform has associated with the formal form and the visualization of music. The frequency spectrum shows that, as the climax of the piece, the sound has a high energy in the range of 300-1000Hz, which is one of the extremely sensitive frequency ranges for human. The composer not only skillfully integrates the chanting of monks with the complex environmental sounds, but also reflects the innovative composition skills. The change of SPL from weak to strong or contrarily is also in line with the emotional expression, that is, the core idea of moving from nature to nature. Since soundscape composition retains more information, it is easier to immerse the audience in the listening process and appreciate the beautiful hope rather than the difficulty of understanding it. In the analysis of soundscape composition, musicological analysis and acoustic analysis are indispensable. © INTER-NOISE 2021 .All right reserved.
