A musician plays a harmonic on the violin.

Definition

1. Adjective:

   • Relating to harmony or musical consonance: Describes sounds that are pleasingly combined, or the study of such combinations.
   • Relating to a harmonic or overtone: Pertaining to a component frequency of a complex sound wave that is an integer multiple of the fundamental frequency.
   • Characterized by sympathetic vibration: In physics, describing vibrations in one body caused by vibrations in another at a specific frequency.
   • Of or relating to harmonics: Concerning the branch of acoustics or music theory that deals with the structure of musical sounds.

2. Noun:

   • A component tone in a complex sound: A pure tone whose frequency is an integer multiple (e.g., 2x, 3x) of a fundamental frequency. These components combine to create the timbre of a sound.
   • An overtone: Specifically, a frequency in the harmonic series above the fundamental pitch.

Examples

• Adjective:

  • The choir produced a beautifully harmonic sound. (The sound was characterized by pleasing consonance.)
  • The guitar string produced a harmonic overtone when lightly touched. (The overtone was part of the harmonic series.)
  • The study of harmonic progression is essential for composers. (It relates to the study of chord sequences in harmony.)

• Noun:

  • The flute's sound is rich in upper harmonics. (The sound contains many component tones at multiples of the fundamental frequency.)
  • When you play a note on a piano, you hear the fundamental pitch plus several harmonics. (You hear the main note and its integer-multiple overtones.)

Advanced Usage

• Harmonic analysis: The mathematical study of functions or signals by representing them as a sum of basic sinusoidal components (harmonics).
  • Fourier transform is a key tool in harmonic analysis.
• Harmonic mean: In mathematics, a type of average calculated as the reciprocal of the arithmetic mean of the reciprocals of the given set of values.
  • The harmonic mean is useful for averaging rates.
• Harmonic minor scale: In music theory, a variation of the minor scale with a raised seventh degree, used for harmonic purposes.
  • The harmonic minor scale creates a stronger pull toward the tonic chord.

Variants and Related Words

• Harmonically (adverb): In a harmonic manner; relating to harmony.
  • The voices were harmonically complex.
• Harmonics (noun, plural): The collective components of a sound that are integer multiples of the fundamental frequency; the study of such phenomena.
  • The engineer analyzed the harmonics of the engine noise.
• Harmonize (verb): To add notes to a melody to create harmony; to make consistent.
  • The singers will harmonize on the chorus.
• Inharmonic (adjective): Not harmonic; lacking the integer-multiple relationship of frequencies, often producing dissonance.
  • The bell's sound was inharmonic and clangorous.

Synonyms

• Consonant (adj): In agreement or harmony; musically concordant.
• Sympathetic (adj): In physics, relating to vibration induced in one body by another.
• Overtone (n): A component of a sound's harmonic series, often used synonymously with 'harmonic' (though technically, the first overtone is the second harmonic).

Related Phrases

• Harmonic series: The infinite sequence of frequencies that are integer multiples of a fundamental frequency.
  • The harmonic series is the basis of musical timbre.
• Harmonic progression: In music, a sequence of chords; in mathematics, a sequence of numbers whose reciprocals form an arithmetic progression.
  • The song uses a classic harmonic progression.
• Natural harmonic: On a string instrument, a clear, flute-like tone produced by lightly touching the string at a nodal point.
  • She played a natural harmonic on the cello.
