Other uses
A perfect fifth is the most consonant harmony, and is the basis for most western tuning systems. Modern musical notation uses a musical staff made of five horizontal lines. In harmonics – the fifth partial (or 4th overtone) of a fundamental has a frequency ratio of 5:1 to the frequency of that fundamental.

A major triad chord when played in just intonation (most often the case in a cappella vocal ensemble singing), will contain such a pure major third.
