In the music of Johann Sebastian Bach, "G major is often a key of 6
8 chain rhythms", according to Alfred Einstein, although Bach also used the key for some 4
4-based works, including his third and fourth Brandenburg Concertos. Pianist Jeremy Denk observes that the Goldberg Variations are 80 minutes in G major.
Twelve of Joseph Haydn's 106 symphonies are in G major. Likewise, one of Haydn's most famous piano trios, No. 39 (with the Gypsy Rondo), and one of his last two complete published string quartets (Op. 77, No. 1), are in G major.
In addition, G major is the home key of Mozart's Eine kleine Nachtmusik, serving as the tonic for three of its four movements (the exception being the second movement, titled Romanze which is in the subdominant key). However, almost none of his large-scale works such as his symphonies or concertos are in this key; exceptions are the Piano Concerto No. 17, Flute Concerto No. 1 and his String Quartet No. 14, along with some examples among his juvenilia.
In popular culture
G major is the key stipulated by Queen Elizabeth II to be used for "God Save the Queen" in Canada. The anthem "God Defend New Zealand" ("Aotearoa") was originally composed by John Joseph Woods in A♭ major, but after becoming New Zealand's national anthem in 1977 was rearranged into G major to better suit general and massed singing. According to Spotify, G major is the most common key of music on the streaming service (closely followed by C major).
