The just perfect fifth can be heard when a violin is tuned: if adjacent strings are adjusted to the exact ratio of 3:2, the result is a smooth and consonant sound, and the violin sounds in tune.

These intervals are called "perfect" most likely due to the way that these types of intervals sound and that their frequency ratios are simple whole numbers.
