Music - Rhythm and Metre


Overview


This refers to how composers use pulse, time signatures and rhythmic devices.

  • What is the tempo? (Try to use specific term such as Andante or Presto)
  • Does the piece change tempo during the piece?
  • Is there an anacrusis/up-beat?
  • What is the time signature?
  • Is there any rhythmic devices? 
    • E.g. Syncopation, Dotted rhythms, Cross rhythms, Polyrhythms, Swung rhythms, Triplets


Note Lengths





Key Features


Metre

The metre of a piece tells us how the beats are grouped in the music, and is indicated by a time signature.

The terms duple, triple and quadruple refer to how many main beats there are in each bar:

  • Duple: two main beats in a bar
  • Triple: three main beats in a bar
  • Quadruple: four main beats in a bar

You can also use the words simple and compound to indicate how the main beat is divided.

  • Simple: each beat divides into two - the upper number of the time signature is 2,3 or 4
  • Compound: each beat divides into three - the upper number of the time signature is 6,9 or 12

So for example 6/8 is compound duple metre because there are two dotted-crochet beats in each bar each of which can be divided into three quavers.

Rhythm - How can we describe it?(Click on the word rhythm for a brief YouTube video)

  •  Pulse/Beat: if you are tapping your feet to or conducting music you are probably tapping out the pulse (e.g. 1 2 3 4)
  • Anacrusis (or upbeat): a note or group of notes that come before the first strong beat in a phrase.
  • Syncopation: this occurs when weak beats or off-beats are accented. Look out for syncopation in jazz, popular music and world music (AOS 3).
  • Dotted rhythms: these are made up of pairs of notes in the pattern long-short. The first note is dotted and the second one is a third of the dotted note's value.
  •  Swung rhythms (jazz): like dotted rhythms but a bit lazier, so the first note is not quite so long and the last not quite so short.
  •  Triplet: 3 notes squeezed in (evenly) in to the space of 1 (e.g. 3 quavers in to the space of 1 crotchet)
  • Cross rhythm: created when two conflicting rhythms occur at the same time, e.g. triplets against normal rhythms
  • Polyrhythm: more than two conflicting rhythms are heard at the same time.
  •  Pause: A wait that interrupts the pulse.
