LifeJohann Christian Bach was born to Johann Sebastian and Anna Magdalena Bach in Leipzig, Germany. His distinguished father was already 50 at the time of his birth, which would perhaps contribute to the sharp differences between his music and that of his father. Even so, his father first instructed him in music and that instruction continued until his death. After his father's death, when Johann Christian was 15, he worked with his second-oldest half brother Carl Philipp Emanuel Bach, who was twenty-one years his senior and considered at the time to be the most musically gifted of Bach's sons.He enjoyed a promising career, first as a composer then as a performer playing alongside Carl Friedrich Abel, the notable player of the viola da gamba. He composed cantatas, chamber music, keyboard and orchestral works, operas and symphonies.Bach lived in Italy for many years starting in 1756, studying with Padre Martini in Bologna. He became organist at the Milan cathedral in 1760. During his time in Italy, he converted from Lutheranism to Catholicism. In 1762, Bach travelled to London to première three operas at the King's Theatre, including Orione on 19 February 1763. That established his reputation in England, and he became music master to Queen Charlotte. He met soprano Cecilia Grassi in 1766 and married her shortly thereafter. She was his junior by eleven years. They had no children.By the late 1770s, his music was no longer popular and his fortunes declined. His steward had embezzled almost all his wealth and Bach died in considerable debt in London on New Year's Day, 1782. Queen Charlotte covered the expenses of the estate and provided a life pension for Bach's widow. He was buried in the graveyard of St. Pancras Old Church, London.[1\]Contrasting styles of J. S. Bach and J. C. BachJohann Christian Bach's father died when Johann Christian was only fifteen. This is perhaps one reason why it is difficult to find points of similarity between the music of Johann Sebastian Bach and that of Johann Christian. By contrast, the piano sonatas of Carl Philipp Emanuel Bach, Johann Christian's much older half brother, tend to invoke certain elements of his father at times, especially with regard to the use of counterpoint. (C.P.E. was 36 at the time J.S. died.)Johann Christian's highly melodic style differentiates his works from those of his family. He composed in the Galante style incorporating balanced phrases, emphasis on melody and accompaniment, without too much contrapuntal complexity. The Galante movement opposed the intricate lines of Baroque music, and instead placed importance on fluid melodies in periodic phrases. It preceded the classical style, which fused the Galante aesthetics with a renewed interest in counterpoint.The symphonies in the Work List for J. C. Bach in the New Grove Bach Family listed ninety-one works. A little more than half of these, 48 works, are considered authentic, while the remaining 43 are doubtful.LegacyA full account of J. C. Bach’s career is given in the fourth volume of Charles Burney's History of Music.There are two others named Johann Christian Bach in the Bach family tree, but neither was a composer.Mozart esteemed J. C. Bach's music highly and arranged three sonatas from the latter's Op. 5 into keyboard concertos.
