Welcome to IFNL.NL – The Home of Vocal Improvisation Retreat 



After two successful editions of the Improvisation Festival in 2019 and 2021, we have decided to take a different approach for the third Dutch edition – a retreat-style experience. While the previous focus was on promotion, concerts, offering skills and making vocal improvisation accessible, this year emphasizes the immersive experience within a small, secure group. The essence lies in singing together in the moment and singing for each other.




Our lineup of vocal improvisation experts is ready to make it all feel remarkably ordinary and within reach. All of this will unfold in a stunning natural setting, offering beautiful accommodations in the middle of the forest, delightful culinary experiences, and the joy of sharing it all with like-minded individuals. And for that last part, you’ll need to contribute your own unique energy.




Join us for a transformative journey where vocal improvisation takes center stage in an intimate and supportive setting. Discover the beauty of spontaneous musical expression, surrounded by nature, comfortable lodgings, delicious meals, and wonderful company.

IFNL.NL – where vocal improvisation becomes an extraordinary retreat.
