Synergy of Music Theatre (SMouTh) is a non-profit performing arts organisation based in Larissa, Greece. Founded in 2001 by a group of young artists returning from studies and professional experience abroad, SMouTh was established with the vision of creating a permanent hub for artistic education, research, creation and expression. Over the last twenty-five years, it has evolved into one of the most active performing arts organisations in regional Greece, combining professional artistic production with education, community engagement and international cooperation. Through year-long educational programmes and a wide range of artistic workshops, SMouTh applies experiential learning and non-formal education methodologies to foster creativity, inclusion, active citizenship and lifelong learning. By bringing together children, young people and adults in collaborative artistic processes, it creates opportunities for personal development, social participation, intercultural dialogue and meaningful engagement with contemporary cultural and social challenges on a local, national and European level.

Alongside its educational activity, SMouTh has built a significant artistic portfolio, producing and co-producing dozens of professional works in theatre, music theatre, opera, dance theatre, theatre for young audiences and interdisciplinary performance. Among its landmark productions are the award-winning opera Carmen (2009), honoured by the Greek Theatre and Music Critics Association, and Paramyfiko (2013, revived in 2018), co-produced with the Greek National Opera. More recent productions include Fidelio (2023), Loop (2024–25), Oleanna (2024–25), and Miss Julie (2025). Several projects and co-productions, such as EUtropia, Un-Label, L – Do I Need Labels To Love, Gravity (and Other Attractions), have received international recognition for their innovative approach to accessibility, inclusion and artistic collaboration. SMouTh is also an active partner in European programmes and networks, including Erasmus+, Creative Europe, ROOTS & ROUTES International, Anna Lindh Foundation, Generation Europe and AJCM, while coordinating the annual MPArt Festival, a key platform for contemporary performing arts in regional Greece.
