MUIC & ACOUTIC – PIANO & KEYBOARD CALCULATOR
Piano String Length
A precise tool.
What is the Piano String Length & How does it work?
The length of a piano string is crucial for determining its pitch. The fundamental frequency ( f ) of a vibrating string is given by the formula:
f = frac{1}{2L} sqrt{frac{T}{mu}}
L = length of the string, T = tension in the string, (mu) = linear mass density of the string
The length of a piano string is inversely proportional to its frequency. Higher notes require shorter strings and higher tensions.

Frequently Asked Questions
How does string length affect a piano’s pitch?
Shorter strings produce higher pitches, while longer strings produce lower pitches.
What is the formula for calculating the fundamental frequency of a piano string?
The formula is f = (1 / 2L) * sqrt(T / ΞΌ), where L is length, T is tension, and ΞΌ is linear mass density.
How do higher tensions affect piano strings?
Higher tensions increase the string’s frequency, resulting in a higher pitch.
What does linear mass density mean for piano strings?
Linear mass density is the mass of the string per unit length and affects how quickly the string vibrates.
Can I use this calculator to find the tension needed for a specific note?
Yes, by rearranging the formula to solve for T given f, L, and ΞΌ, you can calculate the required tension.
How do piano makers ensure each string is the correct length?
Piano makers use precise measurements and calculations based on the desired pitch and material properties of the strings.
What happens if a piano string is too long or too short?
A string that is too long will produce a lower pitch than intended, while a string that is too short will produce a higher pitch.
