C-flat major contains C-flat, E-flat and G-flat. On an equal-tempered piano, its pitch classes match B, D-sharp and F-sharp.
C-flat major contains C-flat, E-flat and G-flat. On an equal-tempered piano, its pitch classes match B, D-sharp and F-sharp. The displayed root-position example is C♭4–E♭4–G♭4. Numbers after note letters identify octaves, not fingers. Use the diagram, note list and bass label together; Play chord sounds the selected notes together, while the note-by-note control sounds them from low to high.
A flat sign does not guarantee a black key. C-flat uses the white B key immediately below the written C. In this root example, C♭4 is the same sounding key as B3, not B4. C-flat to E-flat is a major third and C-flat to G-flat a perfect fifth. The three flat signs preserve the root–third–fifth letter pattern C–E–G. Replacing only one label with its sharp equivalent would obscure that spelling.
Read each bass note before selecting a position. The root-position example starts with C♭; first inversion starts with E♭; second inversion starts with G♭. The chord tones stay the same. These are independently chosen reference registers, not an ascending exercise. Switching a position must update the selected note order, diagram, sound and current-print snapshot together. Hand numbers, when available, apply only to the root example.
| Position | Symbol | Notes, low to high | Bass |
|---|---|---|---|
| Root position, current selection | C♭ | C♭4–E♭4–G♭4 | C♭4 |
| First inversion | C♭/E♭ | E♭4–G♭4–C♭5 | E♭4 |
| Second inversion | C♭/G♭ | G♭4–C♭5–E♭5 | G♭4 |
No verified hand-number examples are currently provided for C-flat major. The chord tones, written spelling, keyboard positions, playback and print reference remain available without assigning a fingering.

C♭4–E♭4–G♭4 and B3–D♯4–F♯4 have identical MIDI values: 59, 63 and 66. They describe the same physical keys with different spellings.
The prepared B-major detail page starts its root example one octave higher. Compare matched registers manually rather than assuming two page defaults should produce identical pitches.
The examples use the site’s ordinary equal-tempered pitch mapping. Keeping C-flat labels does not require a special instrument or a different keyboard layout.
The first inversion is E♭4–G♭4–C♭5, labeled C♭/E♭. C♭5 uses the B4 key. Inversion and octave labels must both remain correct when these notes reach the renderer.
Name the three chord tones before looking back at the answer. Then name the bass of the first inversion. These are written self-checks, not additional scored modes.
No. C-flat is the white key immediately below C, normally labeled B in the same sounding register.
Octave numbers are assigned by the written letter. Lowering C4, MIDI 60, by one semitone gives C-flat4, MIDI 59, the B3 key.
Yes. C major is C–E–G; C-flat major is C-flat–E-flat–G-flat. Every corresponding pitch is one semitone lower.
No verified hand-number examples have been prepared for this page. The missing evidence is not filled by copying another chord’s hand numbers.
The existing builder checks sounding pitch classes rather than written spelling. C-flat and B can therefore count as the same pitch class; this is not a notation-spelling examination.
Select the three pitch classes that make C flat major, then check your answer.
This keyboard checks an unordered pitch-class set. Order, octave, fingering and live piano performance are not assessed.
One octave, C through B. Select a key again to remove it.
