Rhosia

Where music breathes

A chamber music dialogue between two voices, viola and piano, exploring the depth of the classical repertoire.

Alina and Matti performing

Two voices,
one conversation

Duo Rhosia was founded in autumn 2021 by violist Matti Lindholm and pianist Alina Sorjonen. What began as the preparation of two recital programmes has grown into a rich ongoing artistic partnership rooted in years of shared chamber music making. At the core of their repertoire are the great Romantic and late-Romantic sonatas, including Shostakovich, Brahms, Rachmaninoff and Rebecca Clarke, alongside carefully chosen works spanning many periods and styles.

Beyond individual concerts, the duo has undertaken ambitious larger projects, among them an instrumental reimagining of Schubert's Winterreise presented across a six-concert Finnish tour in summer 2024, and performances in London and Dublin in spring 2025. Duo Rhosia has collaborated with Ethno Contemporary Ballet, Klockriketeatern, and a wide circle of musicians and visual artists, expanding their concerts into multidisciplinary experiences. The name Rhosia weaves together the players' initials while evoking the Greek symbol of the rose: beauty, passion, and mystery.

Alina Sorjonen is a pianist, chamber musician, and piano teacher who has served as creative director of the Helsinki Metropolitan Orchestra and Kirkkonummi Chamber Orchestra. She has studied at Metropolia University of Applied Sciences, the Sibelius Academy, the University of Arts Graz, and the Tallinn Music Academy, where she completed her Master's degree in 2017 under Sten Lassmann. Alina has appeared as concerto soloist in Beethoven's Third and Rachmaninoff's Second piano concertos in Finland and Shanghai, and has extensive solo and chamber experience in Italy, France, Austria, and Hungary. Her artistic thinking has been shaped by, among others, Valeria Resjan, Ilmo Ranta, and Barry Douglas.

Matti Lindholm is a violist and teacher with wide-ranging experience across chamber music, orchestral playing, and studio recording. He has performed with the Synkronis Quartet, Hyvinkää Orchestra, Mikkeli City Orchestra, Jakobstads Sinfonietta, Sinfonietta Lentu, Chamber Orchestra La Tempesta, and string quartet Luomus. As a studio musician he has recorded with artists including Kaija Koo, Anna Puu, Lauri Tähkä, and Happoradio. Matti graduated from the Helsinki University of Applied Sciences in 2004 and has attended masterclasses with Miguel da Silva, Antonello Farulli, and Géza Németh of the Bartók Quartet. He plays a viola built in the early 19th century, attributed to Jo. B. Ceruti of Cremona.
