Difference between two sounds of the same pitch?

Timbre is the difference between two sounds of the same pitch. It is the quality that distinguishes one sound from another, even when they have the same pitch and loudness. Timbre is determined by the waveform of a sound, which is a graph of the sound's amplitude over time. The waveform of a sound is determined by the frequencies and amplitudes of the sound's harmonics.

Harmonics are the frequencies that are present in a sound in addition to the fundamental frequency. The fundamental frequency is the lowest frequency in a sound, and it is the frequency that determines the pitch of a sound. The harmonics are multiples of the fundamental frequency, and they give a sound its characteristic timbre.

The timbre of a sound can be changed by changing the frequencies and amplitudes of its harmonics. This can be done by changing the instrument that is playing the sound, or by changing the way the sound is produced. For example, the timbre of a violin sound can be changed by changing the bow pressure, or by changing the position of the bow on the string.

Timbre is an important part of music, and it is used to create different sounds and effects. For example, the timbre of a sound can be used to create a sense of space or to create a particular mood. Timbre is also used to create different textures in music. For example, the timbre of a sound can be used to create a thick or thin texture.
