Symphony Orchestra of Tbilisi State Opera and Ballet Theatre has serious traditions, it was formed as soon as the theatre was founded and from the very beginning was completed by the Georgian and foreign professional musicians.
On opening of the theatre in 1857 the orchestra and the theatre company produced 12 European operas under the guidance of Italian conductor Barbiery. Peter Tchaikovsky who five times visited Georgia in 1886-1890 was delighted with the orchestra and the theatre in general.
The orchestra participated in various performances of foreign opera and ballet companies that came on tour to Georgia. Among these companies were the Russian Ballet Company from Petersburg (1852), Italian opera companies (1897-1898, 1910), Vienna Imperial Operetta (1903), Moscow and Petersburg comic operas (1907), Petersburg Imperial ballet (1907, 1908, 1913).
Since 1860 the orchestra begins independent artistic activities and gives concerts of symphonic music under conduct of Shaning and Katany. In 80-ies of the 19th century the orchestra accompanied such outstanding musicians as Shaliapin, Rubinstein and Rakhmaninov.
During the 20th century the orchestra was conducted by Evgeni Mikeladze, Ivane Paliashvili, Vakhtang Paliashvili, Odyssey Dimitriadi, Shalva Azmaiparashvili, Givi Azmaiparashvili, Jansug Kakhidze.
Since the 30-ies of the 20th century the orchestra together with the theatre company goes on tours to different countries of the world. The tours to a prestigious international musical festival in Hungary – “Segedi International Games” and the 4th international Paris musical festival (France, 1966) were great success. In 1974 the orchestra as well as the theatre company presented three Georgian operas during the days of Georgia in Saarbruken. In 1993 the orchestra and the ballet company of the theatre appeared before the audience in Malta, in the Mediterranean concert hall and in 1994 at Sananders music festival in Spain.
Equally successful was the tour of the orchestra and the theatre opera company in Israel (2003) at the 4th Rishon LeZion international festival – “Classical Spring”.
In 2004 due to the changes made in management of the theatre the staff of the orchestra was renewed.
In 2004-2007 outstanding conductors Manlio Bentz and Shuia Okatsu, soloists Ferucho Furlaneto, Makvala Kasrashvili, Zurab Sotkilava, Badri Maisuradze, Paata Burchuladze, Misheal Kraider, Lado Ataneli, Eter Lamoris, and Iano Alibegashvili appeared with the orchestra on the stage.
The orchestra regularly gives concerts of symphonic and vocal-symphonic music, cooperates with Paata Burchuladze charity foundation “Iavnana.” Concerts of Lado Ataneli, Alexandre Korsantia, Eter and Lamara Tchkhonias arranged lately as well as performance of “Requiem” by Verdi in 2006 proved to be important cultural events.
It is worth of noting that in 2005 a chamber orchestra was organized on the basis of the symphony orchestra and concerts were held with Gogi Chichinadze and Gogi Babuadze conducting, the latter being a conductor whose artistic career at present is connected with Japan.
In 2006 the orchestra and the theatre opera company were great success in Sweden, at the well-known Dalhala opera international festival where “Il trovatore” by Verdi and “Samson and Delilah” by Saint- Saëns were presented.
In 2007, for the first time in the history of the theatre, the opera company and the orchestra were presented at The Days of European Opera, where various European theatres took part.
In April 2008 the troupe of the opera (orchestra, choir, soloists) have appeared with Leoncavallo’s “I pagliacci” and with gala-concerts (conducted by Zaza Azmaiparashvili, Gogi Tchitchinadze, directed by David Sakvarelidze) in several cities of Israel (Jerusalem, Kiryat Haim, Herzliya, Rishon LeZion). After these successful tours the creative troupe of the Theatre performed several times again in various cities and towns of Israel. Also, the creative troupe visited Italy and Spain with tours and twice appeared in Lebanon at Al Bustan International Festival of Music & the Performing Arts, where they are invited again in 2013.  
There has been finished the process of equipping the orchestra with new instruments, made and produced by the various world known firms and masters.
