The Heidelberger Kammerorchester (= HKO) was created in 1960 from a musician circle around Klaus Preis. Since then the HKO has played regularly in concerts in all continents (more than 90 countries). The orchestra is characterised in particular by the fact that it works without recourse to of public means.
The repertoire of the HKO includes mainly compositions from the 18th Century. Beside the popular works of J.S. Bach (Brandenburg Concerts) and Antonio Vivaldi (The 4 Seasons) the orchestra performs works of W.A. Mozart and particularly of Georg Philipp Telemann. Besides also less well-known composers are considered, like Henry Purcell, Tomaso Albinoni, Johann Pachelbel, Pietro Antonio Locatelli, Arcangelo Corelli, Henricus Albicastro, William Boyce, Johan Helmich Roman, Jean-Baptiste Lully, Benedetto Marcello, Jean Marie Leclair and many others.
The concerts take place mainly in Germany, Switzerland and France. A big Spain tour and England/Ireland tour are organized annually. In addition they have appeared overseas (USA, Canada, Japan, Taiwan, China, Korea, Caribbean Islands of the Pacific Ocean, Israel, Malta, in countries of Africa and South America).
