Definition of duple in English:



  • (of rhythm) based on two main beats to the bar.

    ‘duple time’
    • ‘The simple melody derived from a pentatonic scale and the prevailing dotted rhythm in compound duple meter elicit the feeling of a slow, graceful Korean traditional dance.’
    • ‘And what caps this dizzy display is not seriously ordered fugato, let alone a full fugue, but a comically stilted allegro dance in duple rhythm, with octave leaps, mostly in two parts with chordal intrusions.’
    • ‘The sections in sesquialtera can then be conducted by simply altering the even tactus of the opening duple meter to an uneven tactus, without changing the timing of the full tactus beat itself.’
    • ‘Rhythm chants would be based not only on the usual duple and triple meters, but also on unusual meters.’
    • ‘The second issue, the interpretation of time signatures and the relationship between duple and triple time, is more controversial.’


Mid 16th century: from Latin duplus, from duo ‘two’.
