Johann Sebastian Bach - Musical Style

Musical Style

Bach's musical style arose from his skill in contrapuntal invention and motivic control, his flair for improvisation, his exposure to North and South German, Italian and French music, and his devotion to the Lutheran liturgy. His access to musicians, scores and instruments as a child and a young man and his emerging talent for writing tightly woven music of powerful sonority, allowed him to develop an eclectic, energetic musical style in which foreign influences were combined with an intensified version of the pre-existing German musical language. From the period 1713–14 onward he learned much from the style of the Italians.

During the Baroque period, many composers only wrote the framework, and performers embellished this framework with ornaments and other elaboration. This practice varied considerably between the schools of European music; Bach notated most or all of the details of his melodic lines, leaving little for performers to interpolate. This accounted for his control over the dense contrapuntal textures that he favoured, and decreased leeway for spontaneous variation of musical lines. At the same time, Bach left the instrumentation of major works includingThe Art of Fugue open.

Bach's devout relationship with the Christian God in the Lutheran tradition and the high demand for religious music of his times placed sacred music at the centre of his repertory. He taught Luther's Small Catechism as the Thomascantor in Leipzig, and some of his pieces represent it; the Lutheran chorale hymn tune was the basis of much of his work. He wrote more cogent, tightly integrated chorale preludes than most. The large-scale structure of some of Bach's sacred works is evidence of subtle, elaborate planning. For example, the St Matthew Passion illustrates the Passion with Bible text reflected in recitatives, arias, choruses, and chorales. The structure of the Easter Oratorio, BWV 249, resembles The Crucifixion.

Bach's drive to display musical achievements was evident in his composition. He wrote much for the keyboard and led its elevation from continuo to solo instrument with harpsichord concertos and keyboard obbligato. Virtuosity is a key element in other pieces, such as the Prelude and Fugue in E minor, BWV 548 for organ in which virtuosic passages are mapped onto alternating flute and reed solos within the fugal development.

Bach produced collections of movements that explored the range of artistic and technical possibilities inherent in various genres. The most famous example is the Well Tempered Clavier, in which each book presents a prelude and fugue in every major and minor key. Each fugue displays a variety of contrapuntal and fugal techniques.
