Intervals

Definition

Intervals are the distance between two pitches, defined by the number of steps or half-steps that separate them. They are a fundamental aspect of music theory, helping to create melodies, harmonies, and chords. Understanding intervals is essential for recognizing relationships between notes, whether they are played in sequence or simultaneously.
