Acoustic Analysis of Beethoven Piano Sonata Op.110

Abstract

This paper uses phonetic analysis software Praat to extract the fundamental frequency values and energy values of Beethoven’s Piano Sonata Op.110, and examines the acoustic characteristics of Beethoven’s later piano sonatas. The research shows: fundamental frequency values of Piano Sonata Op.110’s three movements range between 80Hz-600Hz, energy intensity values range between 40dB-80dB, and the theme and emotion the composer expressed in each movement and the playing strength will have a certain effect on the changes in the movement’s fundamental frequency and energy.
