(Piano Method). The great Baroque master composer Johann Sebastian Bach (1685-1750) wrote music for every combination of instruments and voices. His simplest and purest work are four-part chorale compositions and settings so perfectly constructed that they evoke meditative spirituality. Figured bass was a Baroque system of notating harmony. In addition 371 chorales this collection includes 69 melodies with figured bass. This classic Schirmer edition edited by Albert Riemenschneider has sold over 1 000 000 copies since its release in the early 20th century. Primarily for keyboard the chorales can also be played by other instruments.
