Extended information:

Pitch is one of the three major characteristics of sound. It is different from sound intensity and timbre. High pitch can only indicate high frequency and short wavelength of sound, but cannot indicate large amplitude and sound. Qiangqiang, many beginners are prone to confusion and misunderstandings about this. We must distinguish the two and not confuse them. The timbre is determined by other bands of the sound (such as overtones). These bands do not affect the pitch, so the pitch has nothing to do with the timbre.
