Interval Identification Worksheet — Major / Minor / Perfect / Aug / Dim

Interval recognition is the foundation under every chord, scale, and melody

Intervals are the atoms of Western music theory: chords are *stacks of intervals*, scales are *step patterns of intervals*, melodies are *sequences of intervals*. Once you can name the gap between two notes instantly, every other theory topic gets faster.

This worksheet drills both halves of the answer: quality (Major / minor / Perfect / Augmented / diminished) and number (2nd through octave). The direction column matters because *ascending* and *descending* feel different to the ear — a descending minor 6th is *Love Story (Where Do I Begin)*, an ascending one isn't.

Mix in a few accidentals (rows with sharps and flats) so students see how a single ♯ or ♭ shifts the interval quality without changing the number — F to C is a perfect 5th, F♯ to C is a *diminished 5th* (the famous tritone).

Pair with ear training: have the student sing each interval after writing it. The combination of written analysis and sung recognition is what makes intervals *stick*. Use with the Scales Reference Chart so students see intervals as *steps within a scale*.
