C-flat major is a musical key that consists of the notes C♭, D♭, E♭, F♭, G♭, A♭, and B♭. It is often considered an enharmonic equivalent to B major, meaning they sound the same but are written differently. C-flat major is less commonly used in compositions due to its complexity, as it contains seven flats in its key signature. In terms of its emotional character, C-flat major can evoke feelings of warmth and introspection. Composers may choose this key for its unique sound, which can add depth to a piece. Notable works in this key include pieces by Frédéric Chopin and Johannes Brahms.
