      How to use it

      1. Choose a difficulty and whether to practise major keys, minor keys or both.
      2. Press New worksheet for a fresh set.
      3. Remember the six pairs: a sharp key and a flat key whose accidentals add up to twelve (for example 6 sharps and 6 flats).
      4. Show answers, or print the answer page separately.

      This worksheet practises enharmonic keys: pairs of keys that use the same pitches but different note names. There are only six such pairs among the standard fifteen key signatures, three major and three minor. In each pair the number of sharps in one key and the number of flats in the other add up to twelve.

      The pairs#

      Sharp key Flat key
      B major (5 sharps) C-flat major (7 flats)
      F-sharp major (6 sharps) G-flat major (6 flats)
      C-sharp major (7 sharps) D-flat major (5 flats)

      The same applies to the minor keys: G-sharp minor and A-flat minor, D-sharp minor and E-flat minor, A-sharp minor and B-flat minor.

      Question types#

      • Name the enharmonic equivalent of a key.
      • Decide whether two named keys are enharmonic (yes or no).
      • Name the key shown by a signature on the staff and its enharmonic twin (medium and hard).
      • Say which spelling has fewer accidentals (hard).

      Difficulty levels#

      • Easy: major keys; naming equivalents and yes or no questions.
      • Medium: adds minor keys and key signatures on the staff.
      • Hard: adds the fewer-accidentals questions.

      Because only six keys qualify, a sheet of twenty questions may reuse a key in a different type of question, but no question appears twice.

      Frequently asked questions

      What are enharmonic keys?

      Two keys with different spellings that sound the same on a keyboard, such as F-sharp major and G-flat major.

      Which major keys are enharmonic?

      B major and C-flat major (5 sharps, 7 flats), F-sharp major and G-flat major (6 sharps, 6 flats), C-sharp major and D-flat major (7 sharps, 5 flats). The minor equivalents are G-sharp minor and A-flat minor, D-sharp minor and E-flat minor, and A-sharp minor and B-flat minor.

      How can I tell which spelling to use?

      Composers usually choose the spelling with fewer accidentals, or the one that fits the music: D-flat major (5 flats) is far more common than C-sharp major (7 sharps), while B major (5 sharps) is more common than C-flat major (7 flats).

      Do enharmonic keys sound identical?

      On a piano and in modern equal temperament, yes. In historical tunings or on instruments that tune freely, the two spellings can differ slightly.
