PianoGridPIANO KEY NAMES / C4–C5

Meet the white keys

One small part of the piano: C4 to C5.

C4C#4Db4D4D#4Eb4E4F4F#4Gb4G4G#4Ab4A4A#4Bb4B4C5

Look for the groups

  • C is the white key just before a group of two black keys.
  • D sits between those two black keys.
  • F is the white key just before a group of three black keys.

Say the names, then find them

Move from left to right: C, D, E, F, G, A, B, C. The letters repeat; the octave number changes at the next C.

Middle C is labeled C4 in this pack. Octave numbers are not finger numbers. This is a reference diagram, not a full-size sticker template.

How to use the pack

Start with the reference

Point out the two- and three-black-key groups. Find the white keys beside and between them.

Try the worksheet

Cover the labels and write the white-key names. Add octave numbers only when they are part of your lesson.

Check and revisit

Compare with the answer page. Revisit the notes that need another look, then optionally try the online practice.

Read the accessible text version

The white keys are C4, D4, E4, F4, G4, A4, B4 and C5.

Black keys form a group of two, then three.

Circle F4; mark the higher C at C5; D4 is between the pair.

The worksheet asks you to name these keys; it does not assess piano technique.

How the labels work

Repeating letter names

White keys repeat C–D–E–F–G–A–B in every octave. Octave numbers such as C3 and C4 name register, not finger numbers.

Black Keys: Sharps and Flats

Black keys sit in repeating groups of two and three. Each black key has two familiar names, such as F♯ and G♭.

Find Middle C

Middle C is C4. Find a group of two black keys, then the white key immediately to their left is a C. Match that C to C4 on the labeled layout.

Labeled keyboard questions

Find a white key immediately to the left of a pair of black keys: that is a C. Not every C is middle C. PianoGrid labels middle C as C4, so use the octave number and the visible keyboard range to identify the correct C.

No. The 4 is an octave or register number in the note name C4. Piano finger numbers are a different system: 1 is the thumb and 5 is the little finger.

No. It is a reference and practice diagram, not a full-size sticker template. If you use physical labels, match them to your own keyboard and follow the label maker’s instructions.

  1. Confirm the instrument’s lowest/highest notes and choose the matching supplied reference.
  2. Locate C before a pair of black keys; choose the correct C octave.
  3. Match and label one C–D–E–F–G–A–B white-key group.
  4. Check the F/G/A/B region against the group of three black keys.
  5. Match the black-key pairs C#/Db, D#/Eb, F#/Gb, G#/Ab and A#/Bb.
  6. Continue through the chosen range, keeping octave suffixes consistent; use the instrument/label instructions for any physical application.

Choose the layout that matches your keyboard

Start with the 88-key reference, A0–C8, or select the 61-key example, C2–C7. Both use letter names and an optional octave suffix, with middle C labeled C4. The 61-key chart describes this specific range; a key count alone does not establish the labels of every keyboard model. Compare the leftmost and rightmost notes with your instrument.

White-Key Names

The white keys repeat C–D–E–F–G–A–B within each numbered octave. Turn octave labels on to distinguish C3 from C4, or A4 from A5. The black-key labels show familiar sharp/flat pairs, such as F♯/G♭. An octave number identifies the note’s register; it is not a finger number or a scale degree.

Label a small section first

First locate a group of two black keys and find the C immediately before it. Match that C to the correct octave in the reference. Next, label the following white keys D, E, F, G, A and B. Check the three-black-key group above F, G, A and B before continuing. Add the sharp/flat names only after the white-key labels match.

How Notes Repeat Across the Keyboard

For the C2–C7 layout, label the leftmost white key C2. Continue through B2, then begin C3, and repeat until the final C7. This layout has six C keys but spans five C-to-C octaves. On the A0–C8 layout, the first three keys are A0, A♯0/B♭0 and B0 before C1. Do not begin that layout with C.

Print a reference you can read

Choose the same layout and octave-label setting for screen and print. Use the marked octave sections to read a long keyboard in smaller pieces. The printout is a reference diagram, not a full-size sticker template. If you use physical labels, match each one to the verified key before applying it and follow the label and instrument instructions for placement.
