From the perspective of musical acoustics, this paper uses the Morning Mood of Bashu Audio-visual Image, composed by Huang Huwei as its research object; collects and records the acoustic source samples of the piano sound of the Morning Mood spread in various locations in the Small Concert Hall of the Music School of Southwest University. By adopting the acoustic analysis software, this paper conducts a comparison analysis and finds the change of the original sound spread in various locations in the concert hall in terms of timbre and loudness, and draws a conclusion based on the quantitative analysis that the loudness on the stage is higher than that under the stage by25%roughly; the timbre on the stage is fuller than that under the stage.
