How does Wolfgang work?

Start Wolfgang before the concert begins. Enjoy the music, while Wolfgang tells you about what you are listening to. You only need to cast a glance at your smartphone every now and then. Wolfgang offers you short, well-timed ‘subtitles’. You will have more than enough time to watch the orchestra and enjoy the music. Wolfgang has been designed not to distract other people. The app works on Wi-Fi or mobile internet (3G or 4G) and uses very little data and battery power. Watch a preview.

Why Wolfgang?

Wolfgang lets you experience the richness of classical music and tells about the stories behind the music. The app points out instruments, explains what they are playing, what it means or what the composer may have had in mind. While program brochures are often rather generic, Wolfgang tells you precisely, from minute to minute, what is happening in the music. Whether you are a seasoned classical music lover or only attend concerts on occasion, Wolfgang will make you listen more attentively and understand the music better.

Wolfgang Phone Mockup


Wolfgang is an initiative of Johan Idema, in close cooperation with Muziekgebouw aan 't IJ and Dutch design agency Fabrique. The app is a showcase of how technology can enrich the live classical concert experience, make classical music more appealing, and increase audience engagement.

The Netherlands Philharmonic Orchestra, South Netherlands Philharmonic, Rotterdam Philharmonic Orchestra and The Hague Philharmonic have been involved from an early stage. Wolfgang texts are written by Marike Verheul, Rick van Veldhuizen, Hugo Bouma and Eline Levering. Wolfgang has been made possible with the generous support of Stichting DOEN and VSBfonds.
