This piece was written for the 50´s anniversary of Prof. Günter Klaus. The song "Happy Birthday to you" is initiated by a citation from the double bass concerto of Dittersdorf, before it sounds walzlike and in major and minor key. Then it is interrupted by "Hoch soll er leben" ("high he should live") and ends with festive Choral character. The whole lasts just three minutes and is held so that it can be played by the professional double bass player without bigger preparation. This little song is the opportunity to hand a musical bouquet to a colleague once a year. It is also available in arrangements for 4, 5, 6 and 8 double basses.
