Joseph Haas was the teacher, Paul Hindemith the model of the director of many years' standing of the Frankfurter Musikhochschule. The ''Heitere Suite'' was created in 1945. ''After a slow introduction (quasi rezitativo) with a viola solo full of suspense, the first violins start playing a succinct, rhythmically accentuated theme dominat-ing the whole movement and appearing in many different forms. Lively intensifications and, not least, the occasional soloistic use of the instruments are giving colour to this work. A valu-able addition to our concert programmes of moderate modern style''.
