Music written in all major and/or minor keys There is a long tradition in classical music of writing music in sets of pieces that collectively cover all the major and minor keys of the chromatic scale. These sets typically consist of 24 numbers, one for the major and minor key of each key signature. Well known examples include Johann Sebastian Bach's "The Well-Tempered Clavier" and Frédéric Chopin's 24 Preludes, Op. 28. Such sets are often organized as preludes and fugues, or designated as preludes or études.
