抄録
The technique of factor analysis is applied to the identification of the tone of sounds of musical instrument. The 26 kinds of sound of two trumpets, which is blowed by one player, are used as the samples. The wave forms of these sounds are decomposed with Fourier transform, and transformed to sets of harmonic amplitude spectra. These sets of relative amplitudes of harmonics, which are normallized for each sound, are the data variables, and they are analyzed with the principal factor method. As a result, although several factors are formally extracted, we can find that only the first factor, which has overwhelmingly large contribution, is physically significant. And also it could be considered that the scores of this factor show the representative pattern of harmonic spectra of the sound of trumpet.
