Abstract
This paper is presented a set of experiments and their results to evaluate the significance of the harmonic
components of Klui-Piang-Aw sound. The experiments are conducted by mean of listening test using three
alternative forced choice (3-AFC). There are 15 subjects who are expert in Thai music involve in the listening test.
The statistical analysis of the experimental results reveals that the second harmonic up to the fifth harmonic are
significant to the sound quality of Klui-Piang-Aw. While the harmonic components from sixth order and higher
are not significant to the quality of Klui-Piang-Aw.
