MUIC & ACOUTIC – MUIC THEORY & HARMONY CALCULATOR
Interval Ratio
A precise tool.
What is the Interval Ratio & How does it work?
In music theory, an interval is the difference in pitch between two sounds. The frequency ratio of an interval is a fundamental concept that describes how much higher one note is than another.
The formula to calculate the frequency ratio (r) for any musical interval is given by:
r = frac{f_2}{f_1}
r = frequency ratio, f_2 = higher frequency, f_1 = lower frequency
Understanding these ratios helps in comprehending the harmonic relationships between notes and is crucial for musicians and composers.

Frequently Asked Questions
How do I calculate the frequency ratio between two notes?
To calculate the frequency ratio, divide the higher note’s frequency by the lower note’s frequency.
What is a frequency ratio in music theory?
A frequency ratio is the numerical relationship between the frequencies of two sounds, describing how much higher one note is than another.
Why is understanding frequency ratios important for musicians?
Understanding frequency ratios helps musicians comprehend harmonic relationships and create more harmonious compositions.
Can you give an example of a common frequency ratio in music?
The frequency ratio for a perfect fifth interval is 3:2, meaning the higher note’s frequency is 1.5 times that of the lower note.
How does this calculator help composers?
This calculator allows composers to easily determine the exact frequency ratios between notes, aiding in the creation of complex harmonies and melodies.
