Duple and quadruple metre

From Wikipedia, the free encyclopedia
(Redirected from Duple time)

Duple metre (or Am. duple meter, also known as duple time) is a musical metre characterized by a primary division of 2 beats to the bar, usually indicated by 2 and multiples (simple) or 6 and multiples (compound) in the upper figure of the time signature, with 2
2
(cut time), 2
4
, and 6
8
(at a fast tempo) being the most common examples.

Shown below are a simple and a compound duple drum pattern.


    \new Staff <<
       \new voice \relative c' {
           \clef percussion
           \numericTimeSignature
           \time 2/4
           \set Score.tempoHideNote = ##t \tempo 4 = 100
           \stemDown \repeat volta 2 { g4 d' }
       }
       \new voice \relative c'' {
           \override NoteHead.style = #'cross
           \stemUp \repeat volta 2 { a8 a a a }
       }
   >>

   \new Staff <<
       \new voice \relative c' {
           \clef percussion
           \numericTimeSignature
           \time 6/8
           \set Score.tempoHideNote = ##t \tempo 4. = 80
           \stemDown \repeat volta 2 { g4. d' }
       }
       \new voice \relative c'' {
           \override NoteHead.style = #'cross
           \stemUp \repeat volta 2 { a8 a a a a a }
       }
   >>

Though the upper number must be divisible by 2, the mere fact that 2 evenly divides the upper figure does not in and of itself indicate a duple metre; it is only a prerequisite.

The most common time signature in rock, blues, country, funk, and pop is 4
4
.[1] Although jazz writing has become more adventurous since Dave Brubeck's Time Out, the majority of jazz and jazz standards are still in "common time" (4
4
).

Duple time is common in many styles including the polka, well known for its obvious "oom-pah" duple feel. Compare to the waltz.

Quadruple metre

[edit]

Quadruple metre (also quadruple time) is a musical metre characterized in modern practice by a primary division of 4 beats to the bar,[2] usually indicated by 4 in the upper figure of the time signature, with 4
4
(common time, also notated as common time) being the most common example.

Shown below are a simple and a compound quadruple drum pattern.


    \new Staff <<
       \new voice \relative c' {
           \clef percussion
           \numericTimeSignature
           \time 4/4
           \set Score.tempoHideNote = ##t \tempo 4 = 100
           \stemDown \repeat volta 2 { g4 d' g, d' }
       }
       \new voice \relative c'' {
           \override NoteHead.style = #'cross
           \stemUp \repeat volta 2 { a8 a a a a a a a }
       }
   >>

    \new Staff <<
       \new voice \relative c' {
           \clef percussion
           \numericTimeSignature
           \time 12/8
           \set Score.tempoHideNote = ##t \tempo 4. = 80
           \stemDown \repeat volta 2 { g4. d' g, d' }
       }
       \new voice \relative c'' {
           \override NoteHead.style = #'cross
           \stemUp \repeat volta 2 { a8 a a a a a a a a a a a }
