The complete organ works by Walther! Johann Gottfried Walther (1684-1748, a near contemporary of Bach) spent the major part of his life as the organist of the Church of St. Peter and Paul in Weimar, where he also was teacher of the Duke of Weimar. He formed a close friendship with Johann Sebastian Bach, of whom he was a second cousin. Walthers organ music may be divided into a large corpus of Chorale settings, in which he followed the tradition of Bach, and the transcriptions of fashionable concertos by composers like Telemann, Albinoni, Torelli, Vivaldi, Gentili and many others.

Dietrich Buxtehude (c. 1637-1707) was a Danish-German composer and organist. He is recognized for bridging Renaissance and Baroque musical traditions, influencing composers such as J.S. Bach and George Frideric Handel. Born in either Helsingborg, Sweden, or Helsingor, Denmark (the exact location remains uncertain), Buxtehude spent much of his career in Lubeck, Germany, where he served as organist at the Marienkirche (St. Mary's Church) from 1668 until his death. As a composer, Buxtehude is recognized for his organ works, including preludes, fugues, and chorale variations. His music blends intricate counterpoint with an expres- sive, almost improvisational character, making him one of the most significant figures in early Baroque music.

Charles-Antoine Campion (later Italianized as Carlo Antonio Campioni) was born in 1720 in the region of Lorraine, France. At age 17 he and his family moved to Florence in Italy, where the young prodigy received lessons from the famous Tartini. After serving for 10 years as Chapel Master of the Livorno Cathedral he was asked by the Grand Duke of Tuscany to move to Florence again and he was appointed Master of the Court Chapel. He became increasingly famous, and he traveled himself to several European capitals (Paris and London) to see to the publication and promotion of his own compositions.
