Carl Philipp Emanuel Bach and the keyboard concerto�a lifelong relationship, challenging and exhaust�ing, altogether fruitful, brilliant, and even spectacular into the bargain. As a 19-year-old (under the eyes of his father, so to speak) he wrote in Leipzig his first keyboard concerto; at the age of 74 in Hamburg he finished, in the year of his death, his last example of the genre. In-between lies a treasury of fifty keyboard concertos, colossal and fathomless. It is a wonder that this uncommonly rich and stylistically influential genre of the composer is only now coming to light. Of all the genres of composition, C. P. E. Bach�s keyboard concertos have guarded their secret longest as unpublished music�that is, precisely the genre of works that qualify as the most personal and most advanced of his compositional oeuvre. He himself says of this: �Because I have had to create most of my works for particular persons and for the public, I have therein always been more constrained than with the few pieces which I prepared just for myself. Among all my works, especially for keyboard, are just a few�concertos, which I composed with total freedom and for my own use.�
