Relationship between pitch and string length

In summary, the relationship between the length of a guitar string and the frequency of the pitch it produces is a linear one, assuming all other variables such as thickness, tension, and material are held constant. This means that if the frequency of the pitch is halved, the length of the string can be halved as well in order to produce the same pitch. This is due to the doubling of frequency when exciting the second harmonic of the string.

Is the relationship between the length of a guitar string and the frequency of the pitch it produces a linear relationship? e.g. If the frequency of the pitch of a string is 60 Hz and I halve the length, should it produce a pitch with a frequency of 120 Hz?

This is assuming all other variables, tickness, tension and material are all held constant.

Yes. Imagine you excite only the second harmonic of the string: the frequency is doubled and the mid point of the string is a node. Putting your finger there and letting half the string vibrate gives the same result.
 

What is the relationship between pitch and string length?

The relationship between pitch and string length is inverse. This means that as the string length increases, the pitch decreases, and vice versa.

How does string tension affect pitch?

String tension also has an inverse relationship with pitch. As the tension in the string increases, the pitch also increases.

What is the mathematical equation for the relationship between pitch and string length?

The mathematical equation for the relationship between pitch and string length is: frequency = (1/2L) * √(T/µ), where L is the length of the string, T is the tension in the string, and µ is the mass per unit length of the string.

What is the role of string material in the relationship between pitch and string length?

The string material also plays a role in the relationship between pitch and string length. Different materials have different densities and stiffness, which can affect the frequency of the string and therefore the pitch.

Does the thickness of the string affect its pitch?

Yes, the thickness of the string, also known as its diameter, can affect its pitch. Thicker strings tend to have a lower pitch than thinner strings due to their mass and stiffness.
