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". Most composers prefer to use the enharmonic equivalent B major, since it only contains five sharps as opposed to C-flat major's seven flats.
Harp parts can also be written in A-flat minor when the rest of the orchestra is notated in G-sharp minor. Sometimes harp parts are also written in G-flat major when the rest of the orchestra is notated in F-sharp major. In Reinhold Glière's Harp Concerto in E-flat major, the middle movement is a set of variations in C-flat major. In Claude Debussy's Sonata for Flute, Viola and Harp, the second movement has a middle section in B major, for which the harp part is notated in C-flat major with seven flats.
In Arnold Bax's symphonic poem Tintagel, the key is B major and again the harp part is always notated in C-flat major but in this case the harp's key signature contains only 6 flats, and the necessary F ♭s are notated with accidentals. This use of C-flat major in harp parts when the rest of the orchestra is playing in B major is not exceptional: it is standard practice in orchestral music written in B major for harp parts to be notated in C-flat major. Thus, in Richard Strauss's Ein Heldenleben, the first cue for the harps is written in C-flat major even though the rest of the orchestra, having previously played in E-flat major, retains a 3-flat key signature and is now playing in B major, marked with the necessary sharps and naturals as accidentals.
