Three friends, three highly experienced chamber music players, sparked by their desire to share the diversity of colour, the immense virtuosity and sheer beauty of their instruments led to the founding of ‚ Trio Roseau‘ in 2012.

Programmes for ‚Reed Trio‘ : Rachel Frost (oboe), Guido Schaefer (clarinet ), Malte Refardt (bassoon), range from the five Divertimenti KV 439b from Wolfgang Amadeus Mozart, through the fine and elegant Viennese classics ( Haydn, Beethoven) , to the sensual 20th century French compositions: Jaques Ibert, Jean Francaix, Darius Milhaud etc. The ‚reed trio‘ itself, combining the three reeded woodwind instruments stems from the 1920’s ‚Trio d’anches de Paris‘ which established together with the Trio Rene Daraux this particular combination of instruments. Trio is a beautiful wind partner to the string quartet enabling ‚Harmonie Musik‘ from the Viennese classics and arrangements from operas to be performed in the finest and most aristocratic venues of the 18th century through to the present day. More modern compositions explore the rhythmic and tonal collage possibilities of the three instruments: Isang Yun, Sandor Veress, the Brazilian Villa-Lobos, so that the trio’s repertoire remains rich in it’s diversity and exploration of colour. Trio Roseau performs at several established music festivals . It is perfectly suited to beautiful buildings and acoustics such as the ‚ Orangerie from Schloss Rheda in the Rheda Weidenbruck musical festival or the idyllic Thusis church as part of the Swiss Domleschger Sommerkonzerten. The trio also includes education work (NDR) children’s Concerts as part of their programme.

CD Trio Roseau Mozart 1

“It is extraordinary to think that you are listening to only three instruments at one time; so good are Ulf-Guido Schäfer’s arrangements, that it sounds like a much bigger ensemble. This is aided by the expert playing of the three musicians who blend their sounds to produce the unexpected.“   (Stuart Sillitoe,

CD Trio Roseau Mozart Vol.2

“The members of the Trio Roseau are excellent Mozartians, sprightly and sensitive. They seem to breathe together, shading their dynamics expertly. They are recorded in a believable space: I feel as if I were in an excellent seat in a real small concert hall.“   (Michael Ullman, Fanfare magazine)

CD Mozart Vol.3

„Virtuosic in the fast parts, generously cantabile in the wide vocal arches: Rachel Frost on oboe and English horn does not miss Mozart’s singer friends at any moment.“ (Vinyl)
