His work has often been looked up to by younger composers including Wolfgang Amadeus Mozart. JS Bach may not have revolutionized musical forms but he gave the musical world models with a mastery of counterpoint, a unique brand of creative polyphony as well as intense spirituality
In March, 1829 (almost 100 years after Bach's death), the composer Felix Mendelssohn performed Bach's St. Matthew Passion, spurring a world-wide interest in Bach. Soon, Bach's works were appreciated by the world - essentially for the first time.
Bach had eye surgery twice in 1749 and became totally blind for a period. Miraculously, his eyesight returned for a while but during the same month, he died of a brain hemorrhage. He died in Leipzig 28 July 1750.
It is well-known that Bach wrote in many more ornaments than the standard practice of his time. In his day, it was the performers' task to add ornaments and embellishments as a part of expressing the music according to its melodic shape, its harmonic progression and associated texture.
This is what Bach was trying to show with his Well-Tempered Clavier sets—that you can play in any key and the music will still sound agreeable. It's sort of the socialist approach to tuning.
Each of the two parts of Inventions and Sinfonias starts with C major, and the pieces are arranged on an ascending chromatic scale until it reaches B minor. There is no duplication of the same keys. When the major and minor keys use the same tonic note, the major key is placed before the minor counterpart, exactly what we also see in the Well-Tempered Clavier.
The Inventions and Sinfonias is a collection of short pieces Bach wrote for the musical education of his young pupils. These are among the finest examples of artistic gems ever written for this purpose, and probably because of this, they became very popular among Bach's pupils and others ever since they were written.
Bach came from a long line of composers - over 300 years' worth of Bachs all worked as professional musicians. By the time Johann was 10, both his parents had died, so he was brought up by his older brother, who was a church organist.
Bach attended Lyceum until 1700. While at Lyceum, he learned reading, writing, arithmetic, singing, history, natural science, and religion. He was forth in his class when he finished his schooling.
Bach composed in many established musical forms, including, for example, the cantata and fugue, and developed them into complex and sublime pieces. He composed over 1,100 works in almost every musical genre (except opera).
