Synonym discussion

Sense: noun/2

Halftone (sense 2), semitone, and half step all refer to the smallest pitch interval in Western music — the distance between two immediately adjacent piano keys. 'Semitone' is the standard term in British and international classical music. 'Half step' is the equivalent term used in American English, common in jazz and popular music contexts. 'Whole tone' (or 'whole step') is twice that distance. 'Interval' is a broader category covering any distance between two notes, from a halftone up to an octave or beyond. Example: 'In the key of C, moving from E to F is a halftone (or semitone), while moving from C to D is a whole tone.'

Etymology

Old EnglishMiddle EnglishEnglish

Formed in English around the 1880s by combining 'half' and 'tone'. The printing meaning was coined when Frederic Ives patented the halftone photographic screen in 1881. The musical meaning (half a tone) existed as a descriptive phrase long before and simply became compressed into one word. Both senses share the idea of 'a half portion of a whole unit' — half of a full tone in music, and half of the tonal range in printing.
