In classical guitar, playing technique affects the tone and expression. The results of FFT(Fast Fourier
Transform) analysis and calculation of overtone content rate showed that the fundamental tone is emphasized
in the apoyando technique, while the overtones are more abundant in the al-aire technique. In addition, the
overtones were divided into consonant interval components and dissonant interval components, and the
consonant interval factor was calculated to evaluate the balanc e between the two components. The results
showed that the al-aire technique had higher factor. We believe that scientific clarification of the difference
in tone between the al-aire technique and the apoyando technique will enable more effective improvement
of tone.
