Pronunciation: [hˈɑːf ɹˈʌn] (IPA) 
The spelling of "half run" can be confusing for some people, as it is not a commonly used phrase. The correct pronunciation is [hæf rʌn], with the stress on the first syllable. "Half" is pronounced with a short "a" sound, like the "a" in "cat", and "run" is pronounced with a short "u" sound, like the "u" in "hut". Together, the words form a phrase that describes a partial or incomplete run, often used in sports or exercise contexts.
Half run is a term used in music to describe a musical ornament or embellishment that involves a rapid ascending or descending movement in a melodic line. This ornamentation technique can be found in various music genres, most notably in baroque and classical music.
When a half run is executed, the performer rapidly plays or sings a sequence of notes that ascend or descend by a half step (also known as a semitone) in a smooth and connected manner. This ornament typically spans over a small melodic interval, usually within one measure or phrase.
The purpose of a half run is to add color, excitement, and ornamentation to a particular musical phrase or section. It often emphasizes tension or creates a sense of anticipation before resolving to a specific note or chord. Half runs are commonly used to decorate cadences, trills, or other melodic passages, allowing the performer to showcase their technical skill while enhancing the overall expression and interpretation of the music.
While half runs are notated using specific symbols or signs in sheet music, such as small grace notes or slurs, the exact execution of the ornament may vary depending on the performer's interpretation and the style of the piece. Skilled musicians are able to execute half runs with precision, agility, and musicality, enriching the overall performance and captivating the listener with their virtuosity.
