SongAttribute

Contains an audio analysis of a song as measured across musical features, mood-based features, and sound and texture features.

Elements

NameTypeDescription
Density string Thickness of the musical sound from 0 to 1. Indicates continuity of sound over time as measured over multiple frequency bands and averaged over each beat throughout the entire track.
DynamicRange string Decibel range from 0 to 70. The value varies by:
  • Musical style
  • Performance
  • How the recording techniques are captured
HarmonicComplexity string How uncommon the harmonic progressions are with regard to principles of music cognition, from 0 to 2.
HarmonicStability string Changeability of harmonic content, from 0 to 1.
  • Shifting harmonic patterns challenge the listener
  • Stable or repetitive patterns create a sense of familiarity and comfort
Loudness string Average audio power throughout the piece, from 0 to 1. Perception of loudness changes as a function of the duration, frequency, and physical strength (amplitude) of the audio signal.
MelodicComplexity string Surprise level of melodic components, from 0 to 2.
MelodicPresence string Presence of a melodic lead—vocal or instrumental—in the musical foreground, from 0 to 1. Vocals buried in the mix, for example, return a lower value.
PerformanceEnergy string Amount of energy or excitement of individual instruments and performers, from 0 to 4.
RhythmicComplexity string Intricacy of the rhythmic patterns that most uniquely define the music, from 0 to 1.
RhythmicIntensity string Rhythmic power, from 0 to 1. An indicator of danceability.
TempoConfidence string Confidence in the TempoPrimary and TempoSecondary ratings, from 0 to 3. Most relevant in music with multiple tempos.
TempoPrimary string Beats per minute, from 0 to 399. Extreme fluctuation and no regular pulse are both reported as a value of 0.
TempoSecondary string Double-time or half-time pace of the music, from 0 to 399.
TexturalStability string Frequency and degree of large-scale textural changes, from 0 to 12. Pronounced changes in texture (timbre) contribute significantly to defining musical form.
Tonality string Brightness of the mood created by the harmonies, from 0 to 1. A lower value indicates a darker mood. This value reflects the dissonance present in each harmony in a piece of music according to its mode (major, minor, etc.).
