What is an overtone and how does it relate to resonance?

In summary, an overtone is any vibration of a body other than its fundamental frequency, which is twice the length of the body. It can be any frequency at which the body resonates, not just a harmonic multiple of the fundamental frequency. This concept can be applied to any wave motion, such as musical tones.

A simple example will illustrate. Hold a string taught and pluck it. It can vibrate many ways, but the end points are fixed. The lowest wavelength (called fundamental) will be 1/2 the string length, others (called overtones) will be multiples of this.

The concept extends to any wave motion (such as musical tones), where the geometry fixes the allowable waves.

An overtone is any other vibration of a body other than its fundamental frequency. The fundamental wavelength of a stretched string is twice the length of the string. A harmonic is an integral multiple of the fundamental frequency.

An overtone is not just any other frequency other than its fundamental. It is any frequency above the fundamental at which a body resonates. It need not be a harmonic.
 

1. What is an overtone?

An overtone is a secondary frequency that is produced along with the fundamental frequency when an object vibrates. It is a natural result of the complex vibration patterns of an object.

2. How is an overtone different from a harmonic?

An overtone is a higher frequency that is produced at the same time as the fundamental frequency, while a harmonic is a multiple of the fundamental frequency. For example, an overtone at 3 times the fundamental frequency would be considered a third harmonic.

3. Can overtones be heard by the human ear?

Yes, some overtones can be heard by the human ear, depending on their frequency and amplitude. Generally, the higher the frequency and amplitude of the overtone, the more audible it will be.

4. How do overtones affect the sound of an instrument?

Overtones play a crucial role in the sound of an instrument. They add depth and richness to the sound, and help to distinguish between different types of instruments. The unique combination of overtones in an instrument's sound is what gives it its distinct timbre.

5. Can overtones be manipulated or controlled?

Yes, overtones can be manipulated and controlled by musicians to create different sounds and effects. This can be done through techniques such as changing the pressure or position of fingers on an instrument, using filters and equalizers in audio production, or even physically altering the structure of an instrument.
