About Us

Orchestra De Cymru

Orchestra De Cymru specialises in themed concerts, accompaniments and the finest 

popular classics in the orchestral, 

operatic & choral repertoire.

​Performance to audiences in Wales is a priority, particularly to those who have little or no other access to live orchestral music, planning to play prominent role in the community through workshops & coaching classes.


The orchestra's membership is drawn from the finest of professional musicians based in Cardiff & further afield.

Having played frequently together over the years, whether as chamber or orchestral musicians, members of the Orchestra de Cymru have vast experience and knowledge of repertoire under their belts.


​Thus equipped, they can tackle any style from baroque to pop, adapting to the requirements of event. They play together as one, able to accompany soloists, choirs, and opera with or without a conductor.

A Viennese Evening or Opera Gala, a Christmas or Easter Celebration, a Valentine’s Night or Summer Serenade, you’ll delight in the musicians’ love of playing.

These concerts sometimes involve childrens’ participation and performance with the orchestra.

Family concerts bring the thrill of live music to the ears of all ages including old favourites such as the ‘Snowman’, 'Carnival of the Animals’, or Peter & the Wolf' as well as fresh newly composed works.

Our workshops give all ages the opportunity to sing opera, conduct or even try an instrument, culminating in performing with the Orchestra De Cymru.

Percussion, brass and string ensembles exist within the orchestra, offering workshops & performances in schools and the community.

Can you Sing Opera


The ensemble from  Orchestra De Cymru brings the thrill of opera to smaller venues. 


    "Many , many congratulations for Sunday...what a sound - mellow and not once          overpowering the singers"


     Patricia O'Neill - "Can You Sing Opera", September 2012


The mainstay of the orchestra's work is accompanying choral works. Accompanying is our forte, whether it be for an opera gala, choral society or concerto. You’ll find us flexible to your needs, as our musicians play together as one with or without a conductor.

"I just want to express on behalf of the Chorale our huge thanks for providing us with an excellent ensemble. 

I thought the orchestral sound  was glorious.....The audience reaction spoke much! 
Apart from your playing, I must say it was good to chat briefly to many of you, and what lovely people you are, friends after all these years."


Martin Hodson - Coleg Gwent Chorale, May 2013
