Dear flute friends,

Thank you for visiting our site.

The Grolloo Flute Sessions bring together three extraordinary fluteplayers Matthias Ziegler, Ian Clarke, Wissam Boustany and flute maker Eva Kingma, brought together by their love of inventive and innovative approaches to the flute; to flute practice, performance, and composition, as well as their highly creative and empowering teaching methods.

This intensive week takes place in the charming village of Grolloo, The Netherlands, where the pioneering flute-maker, Eva Kingma, lives and makes her innovative flutes. The course is structured to maximize the flow of inspiration and ideas between performers and auditors, with the enthusiastic encouragement and support of the village.

You may be interested to participate in Grolloo Flute Sessions.
At this moment we are preparing for Grolloo Flute Sessions 8 in 2023.
Grolloo Flute Session 8 will be 6 days (one day more than previously!). From August 22nd until August 27th, 2023 (arrival on the 21st).

Main features of the week

Opening Concert: Matthias, Ian and Wissam open the course with a joint recital, setting the tone for the week. This concert takes place in the home of an enthusiastic supporter of the course.
Daily Topic of The Day: Themed morning presentations/workshops/discussions.
Daily Video Performance Class: Each participant gives a videoed performance. An open discussion follows in which valuable feedback is given and issues are debated by the whole group, including many enthusiastic Grolloo residents. Participants are given a copy of the video and can study their performance and the discussion in their own time.
Daily Masterclass: These present the opportunity for detailed work on repertoire, to develop and consolidate ideas.
Open Stage Evening/Party: This very special mid-week evening is when the participants’ bond is consolidated. Completely unplanned, improvisations and impromptu performances take place in Eva Kingma’s home. Pure fun and creativity…and no judgment.
Flute Workshop Visit: Participants visit Eva Kingma’s workshop and learn how her wonderful instruments are created.
Church Concerts: These participant-led performances take place in the village church and are attended by a large and enthusiastic local audience, presenting an additional opportunity for participants to perform and consolidate what they have learned.
The Village: A large part of the success of the course is the village itself…the local community is very committed to the course, helping provide accommodation and participating in many of the concerts, classes, and discussions.


Matthias Ziegler, Ian Clarke and Wissam Boustany are presenting an innovative flute course, with the support of Kamelia Miladinova and Eva Kingma.

The Grolloo team places a high priority on creating a welcoming spirit of learning and sharing of ideas amongst all participants, irrespective of age or ability. Thus far, participants have come from across the world and have ranged from those about to start music college, graduates from leading musical institutions, to professional performers and teachers.
Participants will be discussing and experimenting many performance and practice issues in fully interactive discussions and workshops.
