My name is Karl Kreifelts. I was born on April 19, 1958, in Lank-Latum, Germany but now known as Meerbusch. I received my first music lessons at the age of 7 (basic lessons and violin) and additionally with the viola at the age of 11. I self-taught myself composition by studying the great masters through all of the centuries. My first complete composition was at the age of 15 (suite for solo violin in the Baroque style). From 1976 until 1980 I was a member of the National Youth Orchestra of Germany (Bundesjugendorchester). I complete degree studies in dentistry, receiving my license to practice medicine in 1982 and doctorate in 1988. I have my own medical practice in Krefeld, Germany. I am an amateur chamber violinist and viola performer. I am also a member of the Extra Choir of the German Opera on the Rhine in Düsseldorf, Germany. Since approximately 1978, I have composed works for chamber music ensembles (6 cello suites, serenades for 3 violas, 2 string instrument trios, 7 string instrument quartets, B-A-C-H fugues in various keys, variation works for string instrument quartets, 1 piano trio, 1 piano quintet, among others). Performances in private and small public venues.
