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.

𝄞
Bb3 – C5
Melody range across 14 semitones
0.67 beats/note
Across 157.0 beats of melody
Stepwise Motion
Jumpiness
Repeaty
100% Diatonic
Percentage of notes within the song's key.
59% 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
57
Measures how diverse and sophisticated the chord vocabulary is in this song.
Percentile: 57/100 — above average
Melodic Complexity
77
Measures the range, intervallic variety, and rhythmic complexity of the melody.
Percentile: 77/100 — above average
Chord-Melody Tension
49
Measures how much the melody notes clash or harmonize with the underlying chords.
Percentile: 49/100 — below average
Chord Prog. Novelty
49
Measures how unusual or unexpected the chord progressions are compared to common patterns.
Percentile: 49/100 — below average
Chord-Bass Melody
95
Measures the melodic movement of the bass notes across chord changes.
Percentile: 95/100 — 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.

Hookpad is an intelligent music sketchpad that helps you write amazing chord progressions and melodies. It uses the tools of music theory to help you find the sounds you're looking for.

Questions

Everything you need to know about TheoryTab.

TheoryTab is the world's largest database of songs analyzed by their chord progressions and melodies. Each entry breaks a song into its harmonic and melodic components using relative notation, making it easy to see the music theory behind any song.
TheoryTabs are crowd-sourced and community-maintained. Musicians use Hookpad — our intelligent music sketchpad — to transcribe songs by ear, identifying the chords and melodies and entering them in a standardized format that anyone can read and learn from.
Roman numerals represent chords by their position in a key rather than by letter name. For example, in the key of C major, I = C, IV = F, V = G, and vi = Am. This relative notation makes it easy to compare chord progressions across songs in different keys. Click here to learn more about relative notation.
Yes! Anyone can contribute. Visit our Contributor Guide to learn how to use Hookpad to transcribe songs. Your contributions help musicians worldwide learn and understand music theory through real songs.

All of our TheoryTabs are contributed to our site by users like you! Every TheoryTab can be revised at any time by any registered user. Each TheoryTab has a full version history similar to Wikipedia.

To edit a TheoryTab, follow this guide.

Please note: Hooktheory is a collaborative, community-driven project, and maintaining quality and respectful contributions is essential. Users may be flagged if they:

  • Consistently submit inaccurate, misleading, or intentionally incorrect TheoryTabs.
  • Delete or overwrite good work from other contributors without reason.
  • Use offensive, inappropriate, or spammy content in their submissions.
  • Repeatedly ignore transcription guidelines or community feedback.
Relative notation describes chords and notes by their function within a key, rather than by their absolute pitch. This means a I–V–vi–IV progression is the same pattern whether the song is in C major, G major, or any other key — making it much easier to recognize common patterns across songs.
