In musical performance, different playing techniques applied to percussion instruments can
produce rigorous effects on sound characteristics. This work aims to discuss the topic about
playing different percussion skills on the vibraphone and measure the sound spectrum to
study the sound effects of vibraphone due to different kinds of plays. The playing techniques
include dyad (dual notes), triad (triple notes), arpeggiated chord, grace note (acciaccatura),
and roll. The radiated percussion sound of vibraphone bar is recorded and analyzed by fast
Fourier transform (FFT) spectrum analyzer. The time domain response and sound spectrum
are, respectively, presented to show the continuity and timbre effects for different plays. Results
show the temporal response and spectral contents by different playing techniques are
quite different from just single note stroke. The beating phenomenon in time domain can be
specifically interpreted by the frequency spectrum contents. This work presents the quantified
approach in studying percussion instrument sound.
