Composer's Day (June 20 and 21)
The fourth edition of the Day of the Composer will take place on and around Saturday, June 21, 2025. The Day of the Composer turns the Netherlands into one large music station. During the national festival, more than twenty participating cities put their composers in the spotlight with all kinds of activities, such as concerts, workshops, and lectures. City composers are composing a new City Song for the festival. The public can travel along from station to station with the New Music NOW Express (with old railway rolling stock)Live performances take place in the three train compartments and at the stations. Radio station NPO Klassiek and online music platform newmusicnow.nl pay ample attention to Dutch new musical art. The Day of the Composer is an initiative of New Music NOW and is unique in Europe.
With Composer's Day, the Netherlands celebrates the importance, value, and joy of new music. Composers active in our country right now deserve to be heard much more often. That is why they are fully in the spotlight at the festival, in all their versatility. They are visibly present and approachable to the public, give workshops and lectures, curate programs, and offer a 'glimpse into their world.' And, of course, their music is heard. Not only in concert halls, but also on the street, at radio and train stations, and on the train. With Composer's Day, initiator New Music NOW aims to set a movement in motion, because creation and curiosity belong at the heart of musical life.

For true enthusiasts, there is also music to listen to on June 20 (20:30 PM and 05:30 PM) and June 21 (at 19:19 AM (!). See the links at the bottom of the blog.
