Keys & key signatures

Match a key to its signature, then read signatures on the staff. Ten questions, a clear explanation and another chance at missed answers.

How to remember key signatures

Order of sharpsF♯ → C♯ → G♯ → D♯ → A♯ → E♯ → B♯

Order of flatsB♭ → E♭ → A♭ → D♭ → G♭ → C♭ → F♭

  • Sharps: go up a half step from the last sharp to find the major tonic.
  • Flats: the second-to-last flat names the major key.
  • Remember these separately: C major and A minor have no sharps or flats; F major and D minor have one flat, B♭.
  • The relative minor starts a minor third (three half steps) below the major tonic. They share the same key signature.

Take your time with each explanation. Missed questions return later in the session so you can try recalling the answer again.
