Abstract

Analysis of Thai principal notes was carried out for the octave referred to as ‘‘Thang Phiang Aw’’. Four different techniques of digital processing, namely discrete Fourier transform (DFT), short-time Fourier transform (STFT), autoregressive model (AR), and modal distribution (MD) werd used. The results indicated that the modal distribution technique was superior to the others. The main Phiang Aw octave covered the frequencies of 465-940 Hz. The pitches were not constant, which was in contrast to the previous hypothesis of Morton’s.
