Bach’s first pupil was JOHANN CASPAR VOGLER, who received instruction from him in his early days at Amstadt and Weimar and, on Bach’s testimony, was an exceedingly able player. He became organist, and later burgomaster, at Weimar, retaining his professional position. Some Choral Preludes by him for a two-manualed Organ with pedals were engraved about 1737.(185) Other pupils of Bach who became famous were: 1. HOMILIUS, of Dresden. He was not only an excellent organist but a distinguished composer of church music as well.(186) 2. TRANSCHEL, of Dresden. He was a fine musician and performer on the Clavier. There exist in MS. six Polonaises by him which perhaps are superior to those of any composer but Wilhelm Friedemann Bach.(187) 3. GOLDBERG, of Königsberg. He was a very finished player on the Clavier, but without any marked talent for composition.(188) 4. KREBS, Organist at Altenburg. He was not only a player of the first rank, but also a prolific composer for the Organ, Clavier, and of church music. He was fortunate in having Bach’s instruction for nine years.(189) 5. ALTNIKOL, Organist at Naumburg. He was Bach’s son-in-law and is said to have been a very competent player and composer.(190) 6. AGRICOLA, Court Composer at Berlin.(191) He is less known as a composer than as a theorist. He translated Tosi’s(192) _II canto figurato_ from Italian into German and provided the work with an instructive commentary. 7. MÜTHEL, of Riga. He was a good Clavier player and wrote for that instrument. His Sonatas and a Duet for two Claviers attest his ability as a composer.(193) 8. KIRNBERGER,(194) Court Musician at Berlin to the Princess Amalia of Prussia.(195) He was one of the most distinguished of Bach’s pupils, full of genuine enthusiasm for his art and eager to assure its interests. Besides his exposition of Bach’s system of teaching composition, we are indebted to him for the first logical treatise on harmony, in which he sets forth his master’s teaching and practice. The first work is entitled _Kunst des reinen Satzes,_ and the second, _Wahre Grundsätze zum Gebrauch der Harmonie._(196) He served the interests of his art also by other writings and compositions, and was an excellent teacher. The Princess Amalia was his pupil. 9. KITTEL, Organist at Erfurt. He is a sound, though not a finished, player, and is distinguished as a composer by several Organ Trios, so excellent that Bach himself might have written them. He is the sole survivor (1802) of Bach’s pupils.(197) 10. VOIGT, of Anspach,(198) and an organist named SCHUBART(199) were mentioned to me by Carl Philipp Emmanuel as having been Bach’s pupils. He knew nothing about them except that they entered his father’s house after he left it.(200)
