Although finally welcomed into the classical canon – with some trepidation late in the 20th century, mostly among the cognoscenti, Wilhelm Friedemann Bach remains a bit of a cipher to many listeners, among the musical sons of Bach whom they've never heard anything from. The experts who love him attest to his high level of enigmatic eccentricity and his sense of stylistic separation from any other Bach son, and this echoes to some extent what Carl Friedrich Zelter remembered about him long after Bach's death; "As a composer he was driven by a need to be original, to distance himself from his father and brothers." But also, as Zelter continued, "he fell into fussiness, pedantry and futility."
Here is another of Gustav Leonhardt's mixed programmes but this one, unlike the earlier European grand tour ((CD) 426 352-2PH, 4/90), is confined to German repertory and is played not on the harpsichord but on the clavichord. The earliest music is by Christian Ritter, who was born in the mid seventeenth century and who was based mainly in Halle where he was employed as an organist. His Suite in F sharp minor is an appealing work somewhat in the manner of Froberger; the opening Allemande is beautifully written and well sustained and the poignant Sarabande an affecting piece built on a descending octave pattern which gives it the character of a lament.
It was the Bachs who launched the harpsichord on its career as a concerto soloist and the sons did not wait to follow in father's wake; the first of Carl Philipp Emanuel's 52 concertos, spanning more than 50 years, probably just predates the first of JSB's. Neither did they pursue the practice of having more than two soloists. In his F major Concerto (the numbering of which differs from that given in Grove: H410, Wq46) CPE accepts the formal plan of the ritornello but not the concept of its unity of thematic mood; he introduces a diversity that is more like that of the exposition in sonata form—though the resemblance ends there, and the element of contrast is maintained in the 'solo' episodes, not derived from the ritornello material.
It must have been daunting for J.S Bach’s musical sons to work with his huge shadow. The fact that four of his children succeeded in becoming important and influential composers is both remarkable and proof of how extraordinary these men were. C.P.E and J.C Bach are perhaps the most famous of them, and of the other two, J.C.F and W.F, it is Wilhelm Friedemann (1710-84) who perhaps came closest to his father as a composer.
