The time series pattern study of classical guitar tone color

(Approach of the arrival sound quality)

Abstract

When we usually play the classical guitar, we give the impulse excitation to the string using the top of finger and the nail. So, it is difficult to get the enough volume and extension of a guitar sound. It is an important subject to bring the characteristic guitar sound with the wide variety of the tone color as far away as possible. The tone color of guitar is defined as the pattern of the envelope curve joining the peak points of the exciting harmonized frequency. The time series of keeping the envelope curve pattern is estimated for the extension of the tone color. Here, we study the behavior of the extension of the guitar tone color.
