Minor 2nd Interval
The smallest interval in Western music - 1 semitone that creates tension and dissonance in melodies and harmonies.
Theory Fundamentals
Interval Properties
- •Size: 1 semitone (half step)
- •Quality: Minor
- •Sound: Highly dissonant, tense
- •Function: Creates tension, needs resolution
Common Examples
- •C to D♭: (or C#)
- •E to F: Natural semitone
- •B to C: Natural semitone
- •Any note: To its chromatic neighbor
Guitar Applications
Natural Minor 2nds - E→F and B→C
These are the only minor 2nd intervals that occur naturally in the major scale (no sharps or flats needed).
E → F Natural Semitone
1st string open to 1st fret
1st string open
1st string, 1st fret
E to F Natural Semitone
B → C Natural Semitone
2nd string open to 1st fret
2nd string open
2nd string, 1st fret
B to C Natural Semitone
C → C# Chromatic Half Step
Adjacent frets on A string
C (5th string 3rd fret)
C# (5th string 4th fret)
Chromatic Half Step: C to C#
Chromatic Minor 2nd Applications
Melodic Chromatic Passing Tones
C (3rd fret)
Chromatic Ascent: C → C# → D
- • Technique: Adjacent frets create smooth lines
- • Usage: Jazz, blues, classical voice leading
- • Effect: Eliminates melodic leaps
Harmonic Cluster Chords
G-C-F#-Bb cluster (contains multiple minor 2nds)
Dissonant Cluster Example
- • Modern usage: Jazz, contemporary classical
- • Effect: Creates urgency and discomfort
- • Resolution: Demands movement to consonance

Chromatic scale: all minor 2nd intervals
- • Any string: Each fret = 1 semitone higher
- • Practice tip: Use for chromatic scale exercises
- • Theory connection: Foundation of equal temperament
Musical Tension & Resolution
Leading Tone Resolution
Leading Tone Resolution
- • Upward resolution: Leading tone to tonic
- • Downward resolution: 4th degree to 3rd
- • Harmonic drive: Creates forward motion
Musical Examples & Famous Uses

Theoretical Context
Harmonic Function
Sound Characteristics
Very harsh and dissonant. Creates strong urge to resolve. Sounds "crunchy" or "gritty." Almost like two notes fighting each other.
Memory Aid
Think of the minor 2nd as the sound of suspense in a horror movie - it's the musical equivalent of tension that demands resolution. The theme from "Jaws" features prominent minor 2nds that create that sense of impending danger. In classical music, it's often called a "semitone" and is fundamental to chromatic harmony and voice leading.
Historical Development
Natural Semitones on Guitar
E to F: Open 1st string (high E) to 1st fret = minor 2nd. B to C: Open 2nd string (B) to 1st fret = minor 2nd. These are the only natural minor 2nds (no sharps/flats needed).
Adjacent Frets Rule
Universal Rule: Any two adjacent frets on the same string form a minor 2nd. Examples: 3rd fret to 4th fret, 7th fret to 8th fret, etc. This makes minor 2nds the easiest interval to find on guitar!
Related Intervals & Comparisons
Ascending Minor 2nds
E (open) → F (1st fret), G# (4th fret) → A (5th fret)
A (open) → A# (1st fret), E (open) → F (1st fret) on high E string
Harmonic Minor 2nds (Dissonance)
Playing minor 2nds simultaneously creates maximum harmonic tension
Rarely used in traditional harmony except as passing tones or for special effect. Used in modern classical and jazz for color.
Chromatic Scale Foundation
The minor 2nd is the building block of the chromatic scale
Every fret on guitar represents one minor 2nd, making it the fundamental unit of pitch distance
