An overtone is a secondary vibration or sound that occurs in addition to the fundamental frequency of an object or sound wave. It is also known as a harmonic or partial.
Overtone is different from a fundamental frequency in that it is a higher frequency vibration that occurs in addition to the fundamental frequency. It is the result of a complex waveform and contributes to the overall timbre or quality of a sound or object.
Overtone is caused by the physical characteristics and properties of an object or sound wave. These can include the shape, size, and material of the object, as well as the force and manner in which it is set into vibration.
Yes, overtone can be heard by the human ear. However, the ability to perceive overtones varies among individuals and is also affected by the complexity and loudness of the sound.
In music, overtones are used to create different timbres and add richness and complexity to the overall sound. They can also be manipulated through techniques such as overblowing on wind instruments or using harmonics on stringed instruments.
