Variation means change, and especially in the realm of tones, this is a particularly popular means of creating developments. In the programme of the guitarist Tilman Hoppstock, there are works with the designation "Variation" as well as many others, such as "Double", Passacaglia", "Mutazione" or "Capriccio". At the same time, it also reflects the possibilities of variation through the ages, beginning with compositions from the Baroque with Froberger, Buxtehude and Bach, through the Classical period – Beethoven, Carulli and Matiegka –to Romantic guitar music by Willcocks and Tansman, to the Garden of Dreams by contemporary composer Karl-Wieland Kurz, who in turn spreads his "mutations" over a Renaissance theme. © Christophorus
