      Lesson details

      Key learning points

      1. Blues is heavily improvised. Although improvisation is composing on the spot, it is not random.
      2. Musicians use the blues scale, typical blues rhythms and the 12-bar blues chord sequence to structure an improvisation.
      3. A successful improvisation often develops from an initial motif.
      4. We have performed an improvisation over the 12-bar blues chords on the keyboard.

      Keywords

      • Improvisation - a section of music where the melodic ideas are made up on the spot

      • Structure - the different sections within a piece of music or how these sections are organised into phrases

      • Motif - a short musical idea that recurs throughout a piece of music

      Common misconception

      Improvisation means the notes are chosen at random.

      Although improvising means making music up on the spot, it is based on a set of notes or scale and can use repetition. Improvisation often uses fixed stylistic characteristics such as particular rhythms, phrase structures and chord sequences.

      Improvising can be daunting, so suggesting ideas for musical starting points (rhythms and limiting the choice of notes) will help. The singing warm up in the addtional materials can be used to build confidence in reacting to musical instructions to a pulse before trying the improvisation activity.
