Matteo Mastromarino is an Italian clarinetist currently serving as Second Solo Clarinet of the Finnish Radio Symphony Orchestra (Yle RSO) in Helsinki.

Born into a family of musicians, he began his musical journey at the age of three with the Orff method under the guidance of his father Paolo. He started studying the clarinet at seven and graduated eight years later under Antonio Tinelli. He continued his training with Alessandro Carbonare at the Accademia Nazionale di Santa Cecilia in Rome and earned a Master’s degree in Musical Interpretation with Romain Guyot at the Haute École de Musique in Geneva. During his formative years he was a member of the Italian Youth Orchestra and was selected by Riccardo Muti to join the Luigi Cherubini Youth Orchestra.

His career developed rapidly through major successes in international competitions, including the Lisbon International Clarinet Competition, the Malta Woodwind Competition, the Marco Fiorindo International Clarinet Competition, the Saverio Mercadante International Clarinet Competition, and the Ciro Scarponi International Clarinet Competition. In 2016 he received an official recognition from the President of the Italian Chamber of Deputies, Laura Boldrini, during National Music Day.

In 2019 he won the position of Principal Clarinet with the Turku Philharmonic Orchestra in Finland, a role he held until February 2025. During the same period he taught clarinet at the University of the Arts in Turku until 2022. In 2023 he won auditions for Principal Clarinet with both the Orchestra della Toscana and the Orchestra Sinfonica Siciliana, choosing to spend the 2023/2024 season in Palermo. In June 2024 he returned to Finland after winning the audition for Second Solo Clarinet with the Finnish Radio Symphony Orchestra (Yle RSO), the position he currently holds.

Throughout his career Matteo has collaborated extensively with orchestras of the highest level, including the Orchestra of the Accademia Nazionale di Santa Cecilia, the Orchestre National de France, the KBS Symphony Orchestra, the Helsinki Philharmonic Orchestra, Ensemble Les Dissonances, the Copenhagen Philharmonic Orchestra, the Teatro Regio di Torino, the Teatro Carlo Felice di Genova, and many others.

Parallel to his orchestral work, solo performance and chamber music form a central pillar of his artistic identity. He has appeared as soloist with the Turku Philharmonic Orchestra, the Orquestra Metropolitana de Lisboa, the Magna Grecia Orchestra, and the Ensemble ’900 of the Accademia Nazionale di Santa Cecilia, and has performed at major international festivals and venues including the Philharmonie de Paris, the Auditorium Parco della Musica in Rome, Victoria Hall in Geneva, the Festival Pablo Casals, the Ravello Festival, and the Osterfestspiele Salzburg.
