Unit B9 – Accidentals

Accidentals are introduced in Stage B. Students will:

  • learn about sharp and flat signs and what they do
      • therefore they should ideally also learn about tones and semitones
  • learn about natural signs and how they work
  • understand that an accidental lasts until the end of a bar (or to the relevant natural sign).
  • play pieces with sharps/flats/naturals (or a mix) in.

This unit will start to prepare students for Stage C where they are introduced to key signatures.

  • The concept of sharps and flats can be introduced at the piano using markers (e.g. animal erasers or temporary stickers).
  • When this concept is first introduced it can be reinforced by getting students to identify any sharps, flats, or naturals, in their pieces before they play.

Vibrant Music Teachers

  • Accidental Abacus can be used at this level if you remove or introduce double flats and double sharps.
