Learning Outcomes

By the end of this chapter, you will be able to:

Identify quality and quantity of intervals
Name various methods for hearing intervals
Identify intervals within a melody

Intervals

An interval is the distance between two pitches. Intervals are melodic when the pitches are happening one at a time (or one followed by the other). Intervals are harmonic when the pitches are happening at the same time.

Key Terms

Melodic interval: when two pitches sound separately with one following the other
Harmonic interval: when two pitches sound at the same time
Major interval: the interval that naturally happens between do and scale degrees 2, 3, 6, and 7 in a major scale
Minor interval: the interval that naturally happens between do and scale degrees 3, 6, and 7 in a natural minor scale
Perfect interval: the intervals of unison, 4, 5, and 8 in either a major or minor scale
