Zwischen//Zeiten (engl. Between//Times) explores the perception of time, freedom, and imagination in both early and contemporary music. In this project, Sylvia Ackermann (fortepiano), Izabella Effenberg (glass harp), and Katrin Klose (composition) combine contemporary music with the sound of a historical fortepiano by Johann David Schiedmayer (1783), a modern glass harp by Glass Instrument Makers G2, and the slow movements of Mozart’s piano sonatas. These slow movements offer a far greater scope for creativity than the more strictly regulated framing movements. In this context, the multifaceted sound of Ackermann’s fortepiano meets the timeless tones of Effenberg’s glass harp.

Katrin Klose expands Mozart’s music with new interludes - experimenting with unusual timbres and seeking contemporary perspectives to connect the two instruments. Izabella Effenberg complements the program with improvisations on the glass harp. The program can thus be understood as a journey crossing borders on many levels in an in-between space: between times, between musical traditions and performance practices, and between moods and tunings.

Sylvia Ackermann is a pianist feeling at home on various keyboard instruments. However, her passion is devoted to historical fortepianos. On her original instruments, Sylvia Ackermann continuously works on developing a vivid and nuanced touch, which is absolutely essential for playing the diverse and highly variable historical keyboard instruments.

In addition to her work as a concert pianist and teacher, Sylvia Ackermann has always been interested in interdisciplinary projects and collaborates with dancers, actors, and video artists.

In 2009, she founded the “Claviersalon” in Miltenberg on the Main River which brings extraordinary programs and ideas beyond the mainstream to the audience in numerous inspiring concerts on original 18th-century instruments. She performs both as a soloist and in a wide variety of chamber music ensembles. Her main repertoire ranges from the second half of the 18th century to around 1830.

Izabella Effenberg is an internationally acclaimed multi-instrumentalist from Poland based in Germany - a sound explorer between worlds, cultures, and resonances. Her musical journey is guided by curiosity, by deep listening in the moment, and by an unrelentless desire for new forms of expression.

In addition to vibraphone and marimba, she explores a unique universe of sounds: the fragile vibrations of the glass harp, array mbira, waterphone, crotales, and sundrum. For her, each instrument becomes a voice, each timbre a story.

Izabella has been honored with numerous scholarships and awards, including the Cultural Prize of the City of Nuremberg and the competition Women in Jazz Next Generation as well as the Polish jazz award Era Jazz. Since 2014, she has curated her own festival, Vibraphonissimo, in the metropolitan region of Nuremberg – exploring and connecting unusual sound worlds and generating genuine musical encounters. In collaboration with outstanding artists and as an endorser for Yamaha, she brings her vision into new spaces.
