      Lesson details

      Learning outcome

      I can analyse how a composer uses rhythmic devices effectively, and can use some of these in my own composition.

      Key learning points

      1. Rhythmic devices can be effective for creating interesting musical ideas, adding variety and developing ideas.
      2. Common rhythmic devices include syncopation, polyrhythm, ostinato and anacrusis.
      3. In some styles, using cross rhythms, hemiolas, diminution and augmentation can be very effective.
      4. To choose rhythmic devices, consider your desired musical effect as well as what devices are most idiomatic.

      Keywords

      • Polyrhythm - multiple different rhythms playing at the same time

      • Cross rhythm - a polyrhythm in which two or more of the rhythms 'conflict' and feel like they have a different pulse

      • Hemiola - when three notes are played over the duration of two or vice versa, creating the feeling of tempo change

      • Syncopation - where a rhythm emphasises notes in between the main beats

      • Diminution - where the notes in a melody or rhythm are all shortened by the same proportion (e.g. in half)

      Common misconception

      It is important to use lots of different rhythmic devices.

      It is more important to use a few rhythmic devices that are effective and idiomatic for the style, rather than using lots of different rhythmic devices.

      Teacher tip

      This composition is a useful starting point for exploring: composing for percussion; composing for small ensemble; structure; using modes; writing in compound time; using dynamics and articulation; varying texture.
