My Flashcards

Definition

Meaning

A sequence of numbers where the reciprocals form an arithmetic progression.

In music, a series of chords or notes that follow principles of harmony; more broadly, any orderly sequence where elements relate in a pleasing or mathematically defined harmonious manner.

Linguistics

Semantic Notes

Primarily a mathematical term with a specific technical definition; used metaphorically in music theory and occasionally in other fields to describe pleasing sequential relationships.

Examples

By CEFR Level

B2
  • In mathematics, a harmonic progression is a sequence of numbers.
  • The numbers 1, 1/2, 1/3 form a harmonic progression.
C1
  • The divergence of the harmonic series is a classic result derived from the properties of harmonic progression.
  • Composers sometimes structure chord changes based on principles analogous to a harmonic progression.

Mnemonic

HARMonic progression: think of HARMony in music where notes relate pleasingly; here, numbers relate through their reciprocals.

Conceptual Metaphor

ORDER IS HARMONY / MATHEMATICAL RELATIONSHIPS ARE MUSICAL

Common Pitfalls

Translation Traps (for Russian speakers)

  • Avoid translating 'harmonic' as 'гармоничный' (meaning 'balanced/pleasant') in the mathematical sense; the correct term is 'гармоническая прогрессия'.
  • Do not confuse with 'гармонические колебания' (simple harmonic motion in physics).

Common Mistakes

  • Using 'harmonic progression' to mean any pleasant-sounding sequence in non-technical language.
  • Confusing it with 'harmonic series' (the sum, not the progression itself).
  • Misspelling as 'harmonical progression'.

FAQ

Frequently Asked Questions

No. A harmonic progression refers to the sequence of terms (e.g., 1, 1/2, 1/3...). The harmonic series refers to the sum of the terms of an infinite harmonic progression (1 + 1/2 + 1/3 + ...).

In the most common form starting with a positive term, yes, each term is smaller than the previous because you are adding a constant to the denominator of the reciprocal. However, the definition can apply to sequences with negative terms as well.

The concept appears in physics (e.g., acoustics, calculating equivalent resistance or capacitance), computer science (analysis of algorithms), and music theory (as a metaphor for chord sequences).

The simplest infinite harmonic progression is 1, 1/2, 1/3, 1/4, 1/5, ... where the reciprocals (1, 2, 3, 4, 5, ...) form an arithmetic progression with a common difference of 1.
