CAMERATA JUNIOR – Youth Orchestra of the Friends of Music, Orchestra in Residence of the Megaron Athens Concert Hall, was founded in 2010 within the framework of the educational actions of the Society of the Friends of Music. Its goal is to cultivate young talented musicians, foster a spirit of cooperation, and educate them through the valuable experience of group musical activity.
The first teacher and conductor was the violinist Dimitris Semsis (now its conductor emeritus), who, through his teaching and inspiration of the young members, nurtured it into an incubator for future artists. In October 2018, the distinguished concertmaster Nikos Haliassas took over as teacher and conductor, with Aristea Tsichli as assistant conductor and Thanos Kouimtzoglou as teaching assistant during the current season. Wendy Clark, Margarita Plesti and Christina Kaminari have also served as teaching assistants in the past.
The Orchestra counts 80 members, aged 9–26 years, and operates on two levels, training a children’s string ensemble (pure string orchestra) and a youth symphonic ensemble. Its composition is constantly renewed, as new members are added following auditions, while older ones evolve professionally. Participation for members is free of charge and weekly lessons take place every Saturday 15:00–16:30 (children’s section) and 17:00–20:30 (youth section) at the Megaron Athens Concert Hall, where the Orchestra performs regularly.
Camerata Junior has also performed at major venues across Attica (Stavros Niarchos Foundation Cultural Center, Presidential Mansion, Athens Conservatoire, Piraeus Municipal Theatre, Ilioupoli Film Club, municipalities of Kifissia, Zografou, Ymittos, Ilion, etc.) as well as across the country (Thessaloniki Concert Hall, Kalamata Dance Hall, Municipality of Aigialia, International Festivals of Nafplio, Andros, Philippi, Argos, Trikala, Larissa, Sparta, Tinos, Halki, Paros, Rhodes, etc.). It has performed works specifically written for it (by G. Kouroupos, P. Fountas, A. Ntarlas, N. Xanthoulis etc.), while its rich repertoire includes many premier Greek and international performances. The Orchestra has collaborated with the MUSICA–Mixed Choir of the Friends of Music, the Rosarte Children’s Choir and the Friends of Music Choir of Thessaloniki, as well as with leading soloists such as M. Petersen, D. Blumenthal, Ch. Dimaras, D. Semsis, D. Vamvas, D. Kitsos, S. Mourikis, A. Hatzinikolaou, S. Karapanos, S. Kyanidou, V. Karagianni, S. Zhu, and others.
