It was the Kapellmeister’s Jagermeister that fueled the idea of blending J. S. Bach and the Rap styling’s of the Notorious B.I.G, initially for his own disportment, but as the bottle emptied disquietude at the possible vitiation of both “Art” forms gave way to a babbling hubris that thankfully collapsed under the weight of a crushing hangover.

Disporting himself with studied insouciance amongst the boxes of hymnals in the sacristy, the sexton nevertheless felt a growing disquietude (even regret) as he saw the kapellmeister and her two dozen middle-aged singers ascend to choir loft, the effect of their simple, earnest harmonies about to be vitiated by the "Latin drums" setting he had activated on the electric piano the night before under the influence of a spare bottle or two of communion wine.

Bewigged, bothered and bewildered, Kapellmeister Bach evinced some disquietude when, all unannounced, Anna Magdalena flounced into his study only to disport herself by gaily snatching from his hand the freshly-inked last sheet from the 'Art of Fugue' before coquettishly rolling it up as a makeshift spill to light the tapers, thereby vitiating somewhat his sense of marital harmony.

A palpable sense of disquietude spread over the audience as the venerable kappelmeister lurched towards the podium resplendent in a Bermuda tux, and those fears were not vitiated by the realization of those closest to the stage that the maestro's baton was a rather acitve cobra, which began to disport itself among the first violins.

Disquietude overcame the kapellmeister as he performed his organ fugue, thinking he heard the sounds of Hell in it, unaware that his mischievous apprentice had disported herself by doctoring the manuscript, vitiating its impeccable harmonies with parallel fifths and other musical taboos. (by Rudi)
