The Swiss première of Georg Friedrich Haas’ concerto grosso No. 1 for four alphorns and orchestra takes place on 22 April at the Tonhalle in Zurich.

When interviewed about the concerto grosso No. 1, Haas described the alphorns as “the source of another dimension of intonation (overtone chords), used to create contrast and to expand the traditional twelvetone tuning of the symphony orchestra.” Kent Nagano conducts the hornroh modern alphornquartet and the Tonhalle-Orchester Zürich.

Further performances of the piece take place on 23 and 24 April. The concert on 23 April will be broadcast live by SRF II at 20:00. Listen live.
