This piece was written at a time when the composer had the impression that the world was losing the great musicians of jazz. On the whole, it adheres to the traditional A-B-A form, but the A and B parts are complex in themselves: A two-bar introduction is followed by a bluesy theme in C major, then a short through-composed bridge to a section in B minor. After both parts have been repeated, there is a short improvisation section on the C major part, followed by the bridge (this time composed differently), which leads into the actual improvisation part (the B part), which can be freely arranged. After that comes the A-part again (bluesy C-major section - bridge - B-minor section) with transition into a concluding coda.
