MOYSA – The Symphony Orchestra of the Thessaloniki Concert Hall was founded by the Organization in March 2015 as youth orchestra, following the initiative of internationally renowned pianist and then Artistic Director of the Organization, Giorgos-Emmanouil Lazaridis, with an initial donation from the Stavros Niarchos Foundation. 
It is a community of musicians from Thessaloniki and Northern Greece and other regions of the country. Its purpose is to further educate its members in orchestral art and related fields, as well as to enhance social awareness through music. Expanding its reach across Europe and the Balkans, its primary goal is to support and promote young talented Greek musicians. 
To date, MOYSA has collaborated with distinguished conductors such as Ilarion Ionescu-Galati, John Thomas Dodson, Daniel Rowland, Yuri Azevedo, Daniele Gatti, Sami Matus, Miltos Logiadis, Michalis Oikonomou, among others. It has also performed alongside prominent figures of the Greek and international music scene, including Leonidas Kavakos, Zuill Bailey, Vassilis Varvaresos, Giannis Tsitselikis, Dionysis Savvopoulos, Vladimir Mendelssohn, Barbara Hendricks, Simos Papanas, Daniel Jinga and many more. Additionally, it has collaborated with major symphonic ensembles such as the Prague Symphony Orchestra, Cameristi del Teatro alla Scala, Royal Concertgebouw Orchestra, European Union Youth Orchestra (EUYO), the Thessaloniki State Symphony Orchestra, the Athens State Orchestra, and the Thessaloniki Municipality Symphony Orchestra, among others. 
Looking optimistically towards the future, MOYSA as a professional orchestra made up of young musicians, is shaping an exceptionally exciting program from 2025 onward, featuring significant concerts at major music venues in Greece and abroad. This initiative is led by distinguished violinist and Artistic Director of the Thessaloniki Concert Hall, Mr. Christos Galileas.  The orchestra has had  conductors Zoe Zeniodi, Thodoris Papadimitriou, and Michalis Trachalios. 
A highlight of MOYSA’s journey so far has been its outstanding performance at the renowned Athenaeum Concert Hall in Bucharest, following an official invitation from the Greek Embassy in Romania. This concert was conducted by maestro Panagiotis Diamantis, who, as of September 2024, has taken on the role of MOYSA’s principal conductor.
