About SwissDuo
Two musicians. Two distinct voices. A shared passion for transforming familiar melodies into something personal.
SwissDuo brings together Swiss pianist and composer Irina Grebaus and Kazakh cellist and composer Sandi Toka Nova. Based in Zurich, the duo combines classical training with a musical curiosity that spans classical music, pop, jazz, rock and film music.
From PIANOCELLO
to SwissDuo
Previously known as PIANOCELLO, the duo continues its musical journey under the name SwissDuo. The name has changed; the musicians, their creative partnership and their commitment to their listeners remain.
Piano and cello are at the heart of their work — in concert, in the recording studio and at the occasions people choose to celebrate through music.
Familiar melodies.
Their own musical language.
SwissDuo’s arrangements begin with a familiar melody and explore what it can become through the interplay of piano and cello.
The cello can take the role of a singing voice, while the piano shapes the harmony, rhythm and atmosphere. Both instruments have room to lead, respond and surprise. Across different genres, the duo brings a distinctive musical character to each piece.
Their listeners have described them as the musical magicians of piano and cello — an expression that inspired their signature phrase, “Magicians of Piano & Cello”.
