This piece was written for the 50´anniversary of Prof. Günter Klaus.The song "Happy Birthday to you" is introduced by a quotation from the double-bass concert of Dittersdorf. Then it sounds walz-like and in major and minor key and is interrupted by the song "Hoch soll er leben" untill it ends in a festive chant character. The piece lasts only three minutes and can be played by professional double bass players without greater preparation. So it is the opportunity to present to a colleague a musical bouquet of flowers once a year. It is also available in arrangements for 2, 4, 6 and 8 double-basses.
