Master the fundamental building blocks of melody, harmony, and musical expression
Intervals are the distances between notes and the foundation of all music theory. They determine the character of melodies, the quality of chords, and the emotional impact of harmonic progressions. Master intervals to unlock the secrets of musical expression.
A musical interval is the difference in pitch between two notes. Intervals can be measured in semitones (half-steps) and are classified by their size and quality. Understanding intervals is essential because they determine:
Stable, consonant intervals that sound complete and resolved.
Bright, happy intervals that create major chord qualities.
Darker, more emotional intervals that create minor chord qualities.
Altered intervals that create tension and need resolution.
The smallest interval in Western music. 12 semitones = 1 octave.
Count the letter names: C to E = 3rd, C to G = 5th.
Perfect, Major, Minor, Augmented, Diminished.
Unison, Perfect 4th, Perfect 5th, Octave - Completely stable
Major/Minor 3rds and 6ths - Pleasant but not completely stable
2nds, 7ths, Tritone - Create tension, need resolution
0 semitones. Same pitch, perfect consonance.
1 semitone. Smallest interval, creates tension.
2 semitones. Common melodic step.
3 semitones. Foundation of minor chords.
4 semitones. Foundation of major chords.
5 semitones. Strong, stable sound.
6 semitones. The "devil's interval" with maximum tension.
7 semitones. Foundation of power chords.
8 semitones. Melancholic, expressive interval.
9 semitones. Sweet, warm harmonic color.
10 semitones. Essential for dominant 7th chords.
11 semitones. Jazz harmony, sophisticated sound.
12 semitones. Same note, higher pitch.
Intervals create the shape and character of melodies
Chords are built by stacking specific intervals
Dissonant intervals create tension that resolves to consonance
Different intervals evoke specific emotional responses
Root + Major 3rd + Perfect 5th
Example: C - E - G (0-4-7 semitones)
Root + Minor 3rd + Perfect 5th
Example: C - Eb - G (0-3-7 semitones)
Root + Major 3rd + Perfect 5th + Minor 7th
Example: C - E - G - Bb (0-4-7-10 semitones)
Movement by 2nds (Major and Minor)
Smooth, flowing melodic lines
Movement by 3rds, 4ths, 5ths
More dramatic melodic contours
6ths, 7ths, Octaves and beyond
Bold, expressive melodic statements
