Pfarreimusik Wünnewil-Flamatt requested a new work to be commissioned for the celebration of its 111th anniversary. They asked the composer to create a piece lasting approximately 11 minutes and 11 seconds. The band asked Jan Van der Roost to reflect on a number of aspects from the past, as well as the current state of affairs. The piece contains lyrical movements, cheerful and jubilant parts, as well as light introverted sequences. Fantasia Helvetica is a varied concert piece with a number of challenging passages, but is also fun to play!
