He now specializes in leading semi-professional choirs and orchestras, which have a rather high musical level in Holland. This makes the work of leading these ensembles a fascinating combination of musical education and serious music making, which is a challenge to a professional musician. His main field of interest is music of the 16th, 17th and early 18th century, from Ockeghem, Obrecht and Josquin via Monteverdi’s Vespers and Schütz to the world of renaissance and baroque music theatre and oratorio.
Dirkjan Horringa works with several vocal ensembles all over the Netherlands and the La Pellegrina ProjectOrkest. He worked as a guest conductor to the Czech vocal ensemble Vaganti, the Ukrainian vocal ensemble Musitchnyj Asamblej (Kiev), the Lithuanian vocal ensemble Brevis (Vilnius) and the choir Confido Domino (Minsk, Belarus). He has been a tutor in several summer schools in Italy, Poland, France and the Czech Republic.
He is privately active as a singing tutor and vocal coach. For many years he taught conducting for the Dutch national choral organization Unisono.
