Marianne Keller Stucki graduated with a teacher's diploma from the vocational school of Bern Conservatory which she entered after visiting the Marzili seminar. She received her concert diploma with distinction from the 'Akademie für Musik und Darstellende Kunst, Wien' (the Academy for Music and Performing Arts in Vienna) after studying under professor Hans Rezniček (member of the philharmonic), and was influenced by Joseph Mertin (ancient music) and Friedrich Cerha (avant-garde). She attended master courses headed by Marcel Moyse, Jean-Pierre Rampal and Aurèle Nicolet in Hamburg and at the 'Musikakademie Berlin' (Berlin Academy of Music). Stucki holds a teaching position at the 'Konservatorium für Musik, Bern' (Conservatory for Music in Bern).
Since her debut in the 'Mozartsaal' of the Viennese Concert House with Mozart's flute concert in G major together with the Viennese Chamber Orchestra, she has concerted extensively, as a soloist and as a chamber musician, and toured with the Trio Elvetico. She has also been seen performing with the 'Berner Duo' (partner Hans Walter Stucki), the Trio Sorop and most recently in a trio with the Czech master violist Lubomír Malý.
While searching for original literature rarities are sometimes uncovered which motivate composers to produce work, such as Arthur Furer's trio 'Reminiszenzen'. Works from other composers such as Rudolf Kelterborn, Bernard Reichel, Victor Fenigstein and Fernande Peyrot, a composer from Geneva, also enrich the programs. She has performed in the triple concert by Vincent d'lndy under Swiss conductors such as Armin Jordan, Räto Tschupp and François Pantillon. The modern style is also represented by trios from Bohuslàv Martinů, Gabriel Pierné, Florent Schmitt, Charles Haubiel, Eugène Goossens and Norman dello Jojo.
Several of these works have been recorded by radio stations, broadcast by television and recorded onto LP.
