ab3

Ab3 is primarily used to denote a musical pitch: the A-flat note in the third octave, written in Western tonal notation and used in various tuning systems such as equal temperament. It is enharmonically equivalent to G-sharp in the same octave, meaning they occupy the same pitch on a standard piano. In standard tuning, Ab3 lies around 207.65 Hz, and it appears in melodies and harmonies across classical, jazz, pop, and other genres. The note is a common component in scales that include flats, such as Ab major or Db major, and it can function as a root, third, fifth, or other scale degree depending on the musical context.

Beyond music, Ab3 can appear as an abbreviation, code, or model designation in other domains. Because it is not tied to a single, universal meaning, its interpretation depends on the surrounding context, such as documentation, product catalogs, or field-specific nomenclature. If encountered outside of musical notation, clarification from the source is typically required to determine the intended meaning.

In summary, Ab3 most often refers to the A-flat note in octave 3 in musical contexts, with other uses being context-dependent and ambiguous without additional information. See also: A-flat, G-sharp, Ab major notes, and related octave designations.
