About the Melody
Melody data is compiled from all analyzed melody sections, so depending on how a user analyzed a song, "melody" might include instrumental notes.
A3 – E6
Melody range across 31 semitones
1.33 beats/note
Across 192.0 beats of melody
Stepwise Motion
Jumpiness
Repeaty
95%
Diatonic
Percentage of notes within the song's key.
67%
Chord Tones
Percentage of notes that fall on a chord tone of the underlying harmony.
Mixed
Consonance
How smoothly the melody blends with the harmony (0 = dissonant, 1 = consonant).
Loose
Syncopation
How often the melody emphasizes off-beats. Higher = more syncopated.
About the Metrics
Chord Complexity
Chord Complexity tracks when a song goes beyond simple three-note chords—either by adding extra tones (like 7ths or add9s) or by borrowing notes from outside the key—creating richer, more sophisticated harmonies.
Melodic Complexity
Melodic Complexity reflects two factors: the use of notes outside the key and rhythmic syncopation, together capturing how intricate or surprising a melody feels.
Chord-Melody Tension
Chord-Melody Tension quantifies how often melody notes fall outside the current chord, producing dissonance that creates a sense of instability.
Chord Progression Novelty
Chord Progression Novelty measures how uncommon a song's chord changes are compared to others in the Hooktheory database, highlighting progressions that deviate from typical patterns.
Chord-Bass Melody
Chord–Bass Melody evaluates how smoothly the bass moves between chords, scoring higher when it travels step-wise, ascending or descending, instead of jumping directly between root position chords.
Hooktheory's metrics are calculated against the entire database of analyzed songs, where 50 is the "average song." Learn more about each of these metrics here.
Chord Complexity
93
Measures how diverse and sophisticated the chord vocabulary is in this song.
Percentile: 93/100 — above average
Melodic Complexity
86
Measures the range, intervallic variety, and rhythmic complexity of the melody.
Percentile: 86/100 — above average
Chord-Melody Tension
29
Measures how much the melody notes clash or harmonize with the underlying chords.
Percentile: 29/100 — below average
Chord Prog. Novelty
82
Measures how unusual or unexpected the chord progressions are compared to common patterns.
Percentile: 82/100 — above average
Chord-Bass Melody
57
Measures the melodic movement of the bass notes across chord changes.
Percentile: 57/100 — above average

Melodic Intervals
Distribution of note-to-note jumps in semitones (negative = downward, positive = upward)
Note Durations
How long each note is held (in beats)
Syncopation
How many notes fall on each level of metric strength (0 = on-beat, higher = increasingly off-beat)
Level 0
Notes that fall on the downbeat — the strongest metric position in the measure.
Level 1
Notes on a secondary strong beat (e.g. beat 3 in 4/4) — still firmly on the grid.
Level 2
Notes on the remaining primary beats (2 and 4 in 4/4) — moderate metric weight.
Level 3
Notes on eighth-note offbeats — between the primary beats. Audibly syncopated.
