The analysis of music s from the perspective of acoustics has its own advantages that cannot be replaced by the traditional musicology. Based on music named Dayb for a hope to overcome COVID-19, this paper analyzes the acoustic elements of , frequency spectrum and waveform. Combined with the traditional musicology, it can show that the undulation of waveform has associated with the formal structure and the visualization of music.
