C flat

musical note which is one half-step lower than the note C

Also see: C major, or C minor. C-flat major is a major scale based on C-flat, consisting of the pitches C-flat, D-flat, E-flat, F-flat, G-flat, A-flat, B-flat and C-flat. The note C-flat is actually B. Its key signature has seven flats (see below: Scales and keys).Its relative minor is A flat minor, and its parallel minor is C flat minor, usually replaced by B minor, since C flat minor has ten flats and therefore is impractical to use.Its enharmonic equivalent is B major, and is more often used in the music that used it as the main key for a composition, usually Irish music. In some manuscripts, the C flat major key signature in the bass clef is written with the flat for the F on the second line from the top.
