Johann Sebastian Bach

Johann Sebastian Bach (31 March 1685 – 28 July 1750) was a German composer and organist whose sacred and secular works for choir, orchestra, and solo instruments drew together the strands of the Baroque period and brought it to its ultimate maturity. Although he introduced no new forms, he enriched the prevailing German style with a robust contrapuntal technique, an unrivalled control of harmonic and motivic organisation in composition for diverse instrumentation, and the adaptation of rhythms and textures from abroad, particularly Italy and France.

Revered for their intellectual depth, technical command and artistic beauty, Bach’s works include the Brandenburg concertos, the Goldberg Variations, the Partitas, the Well-Tempered Clavier, the Mass in B Minor, the St. Matthew Passion, the St. John Passion, the Magnificat, The Musical Offering, The Art of Fugue, the English Suites, the French Suites, the Sonatas and Partitas for violin solo, the Cello Suites, more than 200 surviving cantatas, and a similar number of organ works, including the celebrated Toccata and Fugue in D Minor.

While Bach’s fame as an organist was great during his lifetime, he was not particularly well-known as a composer. His adherence to Baroque forms and contrapuntal style was considered “old-fashioned” by his contemporaries, especially late in his career when the musical fashion tended towards Rococo and later Classical styles. A revival of interest and performances of his music began early in the 19th century, and he is now widely considered to be one of the greatest composers in the Western tradition.

Music – Influences and Style

Bach’s musical style arose from his extraordinary fluency in contrapuntal invention and motivic control, his flair for improvisation at the keyboard, his exposure to South German, North German, Italian and French music, and his apparent devotion to the Lutheran liturgy. His access to musicians, scores and instruments as a child and a young man, combined with his emerging talent for writing tightly woven music of powerful sonority, appear to have set him on course to develop an eclectic, energetic musical style in which foreign influences were injected into an intensified version of the pre-existing German musical language. Throughout his teens and 20s, his output showed increasing skill in the large-scale organisation of musical ideas, and the enhancement of the Buxtehudian model of improvisatory preludes and counterpoint of limited complexity. The period 1713-14, when a large repertoire of Italian music became available to the Weimar court orchestra, was a turning point. From this time onwards, he appears to have absorbed into his style the Italians’ dramatic openings, clear melodic contours, the sharp outlines of their bass lines, greater motoric and rhythmic conciseness, more unified motivic treatment, and more clearly articulated schemes for modulation.

There are several more specific features of Bach’s style. The notation of baroque melodic lines tended to assume that composers would write out only the basic framework, and that performers would embellish this framework by inserting ornamental notes and otherwise elaborating on it. Although this practice varied considerably between the schools of European music, Bach was regarded at the time as being on one extreme end of the spectrum, notating most or all of the details of his melodic lines-particularly in his fast movements-thus leaving little for performers to interpolate. This may have assisted his control over the dense contrapuntal textures that he favoured, which allow less leeway for the spontaneous variation of musical lines. Bach’s contrapuntal textures tend to be more cumulative than those of Händel and most other composers of the day, who would typically allow a line to drop out after it had been joined by two or three others. Bach’s harmony is marked by a tendency to employ brief tonicisation-subtle references to another key that lasts for only a few beats at the longest-particularly of the supertonic, to add colour to his textures.
