Overview

Intervals are the distances between notes. They define melody, harmony, and the emotional character of music. Guitarists who recognize intervals by ear can improvise more musically, transcribe faster, and understand what they’re hearing in real time.

These five intervals form the core vocabulary of modern guitar playing.

1. Minor Third

A minor third spans three half steps. It is the defining sound of minor chords and minor melodies.

Emotional quality: Sad, introspective, dark. Guitar shape: Three frets up on the same string.

2. Major Third

A major third spans four half steps. It creates the brightness of major chords.

Emotional quality: Warm, stable, uplifting. Guitar shape: Four frets up on the same string.

3. Perfect Fourth

Five half steps. This interval is everywhere in guitar tuning—between most strings.

Emotional quality: Open, neutral, strong. Musical role: Common in riffs, power chords, and melodic movement.

4. Perfect Fifth

Seven half steps. This is the interval that defines power chords.

Emotional quality: Strong, stable, foundational. Guitar shape: Two frets up and one string down.

5. Minor Seventh

Ten half steps. This interval gives dominant chords their tension and bluesy color.

Emotional quality: Tense, soulful, unresolved. Musical role: Essential in blues, funk, rock, and jazz.

How to Train Your Ear

• Sing the interval before playing it.
• Play the interval on one string to hear the pure distance.
• Identify intervals in songs you already know.
• Practice intervals ascending and descending.
