Characteristics
Like F-sharp major, G-flat major is rarely chosen as the main key for orchestral works. It is more often used as a main key for piano works, such as the impromptus of Chopin and Schubert. It is the predominant key of Maurice Ravel's Introduction and Allegro for harp, flute, clarinet and string quartet, and is also used in the second movement "Le Gibet" of Ravel's famous Gaspard de la nuit.
A striking use of G-flat major can be found in the love duet "Tu l'as dit" that concludes the fourth act of Giacomo Meyerbeer's opera Les Huguenots.[citation needed]
When writing works in
Antonín Dvořák composed Humoresque No. 7 in G-flat major, while its middle section is in the parallel key (F-sharp minor, enharmonic equivalent to the theoretical G-flat minor).
This key is more often found in piano music, as the use of all five black keys allows an easier conformity to the player's hands, despite the numerous flats. In particular, the black keys G♭, A♭, B♭, D♭, and E♭ correspond to the 5 notes of the G-flat pentatonic scale. Austrian composer Franz Schubert chose this key for his third impromptu from his first collection of impromptus (1827). Polish composer Frédéric Chopin wrote two études in the key of G-flat major: Étude Op. 10, No. 5 "Black Key" and Étude Op. 25, No. 9 "Butterfly" as well as a waltz in Op. 70. French composer Claude Debussy used this key for one of his most popular compositions, La fille aux cheveux de lin, the eighth prélude from his Préludes, Book I (1909–1910). The Flohwalzer can be played in G-flat major, or F-sharp major, for its easy fingering.
John Rutter has chosen G-flat major for a number of his compositions, including "Mary's Lullaby" and "What sweeter music".[5] In a charity interview[6] he explained several of the reasons that drew him to this key. In many soprano voices there is a break round about E (a tenth above middle C) with the result that it is not their best note, bypassed in the key of G-flat major. It is thus, he claims, a very vocal key. Additionally, writing for strings, there are no open strings in this key, so that vibrato can be used on any note, making it a warm and expressive key. He also cites its facility on a piano keyboard.
