Our Story

Timeless Training. Modern Sound.

We grew up making music together: Felicitas plays the violin and sings, while Jonas plays piano and later added the cello. Our childhood unfolded between rehearsals, competitions, and school orchestras, followed by opera for Felicitas, a big band for Jonas, and periods of classical training in Novosibirsk, Siberia.

Music gave us a language for things we did not yet know how to say. Learning it took patient teachers, years of devoted practice, and a family whose love and encouragement made it all possible. We feel deeply fortunate for that.

Together, we went from Jugend musiziert to the Laeiszhalle and, in 2025, Carnegie Hall. After years of interpreting other people’s music, we began wondering what our own might sound like. Being Brave is our first answer — and the notebook is already full of ideas for what comes next.

MeetFelicitas

Felicitas is my sister and has been by my side for all but 20 months. At five, we began making music: her violin, my piano. Her full name is Hanna Felicitas, but even as a baby, she radiated such warmth and optimism that our parents called her Felicitas — “the happy one.” That joy is matched by rare honesty and courage: she faces life’s biggest questions and its difficult parts head-on, never pretending they aren’t there. All of this lives in her voice. I’m constantly amazed by who she is and who she is becoming—and deeply grateful to create beside her as her brother.

MeetJonas

Jonas isn’t simply my older brother in music, he playfully uncovers the richest, deepest, most cheerful colors.
He has my back in everything I do, inspires me to make it happen, because with strength and passion, he devotes himself to making his own dreams come true.
As determined as he is, as gentle is the soft-hearted spirit that in him lives.
At times, I think we are polar opposites, but what we long for as soloists is what we find in each other’s harmonies, creating soulful fireworks and hopeful symphonies when my heart sings and my brother’s heart swings.
