Johann Sebastian Bach was a German composer and musician of the Baroque period. He enriched established German styles through his skill in counterpoint, harmonic and motivic organisation, and the adaptation of rhythms, forms, and textures from abroad, particularly from Italy and France. Bach's compositions include the Brandenburg Concertos, the Goldberg Variations, the Mass in B minor, two Passions, and hundreds of cantatas. His music is revered for its technical command, artistic beauty, and intellectual depth.

Bach's abilities as an organist were highly respected during his lifetime, although he was not widely recognised as a great composer until a revival of interest in and performances of his music in the first half of the 19th century. He is now generally regarded as one of the greatest composers of all time.

Georg Philipp Telemann (14 March 1681 – 25 June 1767) was a German Baroque composer and multi-instrumentalist. Almost completely self-taught in music, he became a composer against his family's wishes. After studying in Magdeburg, Zellerfeld, and Hildesheim, Telemann entered the University of Leipzig to study law, but eventually settled on a career in music. He held important positions in Leipzig, Sorau, Eisenach, and Frankfurt before settling in Hamburg in 1721, where he became musical director of the city's five main churches. While Telemann's career prospered, his personal life was always troubled: his first wife died only a few months after their marriage, and his second wife had extramarital affairs and accumulated a large gambling debt before leaving Telemann.
Telemann was one of the most prolific composers in history (at least in terms of surviving oeuvre) and was considered by his contemporaries to be one of the leading German composers of the time—he was compared favorably both to his friend Johann Sebastian Bach, who made Telemann the godfather and namesake of his son Carl Philipp Emanuel, and to George Frideric Handel, whom Telemann also knew personally. Telemann's music incorporates several national styles (French, Italian) and is even at times influenced by Polish popular music. He remained at the forefront of all new musical tendencies and his music is an important link between the late Baroque and early Classical styles.
