Perfect fifth

Definition

A perfect fifth is a musical interval that spans seven half steps, or semitones, between two notes. This interval is highly consonant and stable, often used in both melody and harmony to create a sense of resolution. The perfect fifth plays a significant role in building chords and harmonizing melodies, providing a foundational element in various musical styles, especially within the realm of electronic arrangements.
