      How to use it

      1. Choose the clef; mixed gives treble and bass questions together.
      2. Choose the task: the full name such as F♯4, or just the octave number.
      3. Choose a difficulty and press New worksheet.
      4. Print and write each answer; middle C is C4 throughout.

      What this worksheet practises#

      Knowing a note’s letter name is half the job; the other half is knowing which octave it is in. Scientific pitch notation adds a number: middle C is C4, and the number goes up by one at every C. This sheet shows a note and asks for its full name, or only the octave number.

      The one rule#

      The octave number changes at C, not at A. So the notes from middle C up to the B above it are all in octave 4: C4 D4 E4 F4 G4 A4 B4. The next C is C5. Going down, the B just under middle C is B3.

      How the levels differ#

      • Easy: notes on the lines and spaces of the staff.
      • Medium: up to two ledger lines.
      • Hard: up to three ledger lines, with sharps and flats.

      Tips#

      Learn a few anchors: middle C is C4, the treble clef’s G line is G4, and the bass clef’s F line is F3. From any anchor, count letters up or down and change the octave number whenever you cross a C. For example, from B4 stepping up gives C5, and from C4 stepping down gives B3.

      Some instrument makers number middle C differently, so when you see a C3 or C5 elsewhere, check which convention is used.

      Frequently asked questions

      What is scientific pitch notation?

      A system that names each pitch by letter plus octave number, such as A4 or C5. The number changes at each C.

      Which note is C4?

      Middle C. The note just below it is B3, and the note just above it is D4.

      What is A4?

      The A above middle C, which is the usual tuning reference at 440 Hz.

      Do all sources agree that middle C is C4?

      Most do, but some keyboard and software conventions call middle C C3 or C5, so check the convention when using other materials. This worksheet always uses C4.
