24 Studies (aus dem "Wohltemperierten Klavier") These 24 Studies have been transcribed from the fugues of The Well-Tempered Clavier, Book I, written by J.S.Bach in 1722. The use of each of the twelve major and minor keys offered a unique collection for the period and stands as a landmark in the history of music. Bach intended that the performer should have a great deal of freedom in interpreting this work. In this edition for trumpet, tempos have been indicated in general terms rather than with specific metronome markings.
