However, the middle section of Frédéric Chopin's Contredanse in G-flat major is written in C-flat major, as are the middle (Trio) sections of two of Ernesto Nazareth's Brazilian tangos for piano, "Chave de Ouro" and "Labirinto" (both with a home key of G-flat major), as well as the final half (last two themes) of William Bolcom's rag for piano, "Seabiscuits".

There is a brief passage in the first movement, "Evocación", of Iberia by Isaac Albéniz which suggests the key of C-flat minor by adding the necessary three double-flats as accidentals.

[2] In some scores, 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.

This can be seen, for example, in the Albéniz example given above: Iberia, 1st movement: "Evocación", about two-thirds of which is in 7 flats, and every bass-clef staff of which shows this variant.

This is also seen in the second movement of the Beautiful Danube waltz in the Boosey & Hawkes concert band edition.
