Established in 2002, the Cambria String Quartet is one of the finest, most experienced quartets in the region.


My name is Helina Rees. I run the Cambria String Quartet from my home on the South Wales coast, my husband helps a little, and my very young daughters occasionally answer the phone!

In terms of both musical quality and levels of service, the Cambria String Quartet is one of the finest around, and I take a lot of pride in our work – I simply wouldn’t do it otherwise. Further down this page you’ll find a selection of the players who play for the quartet – all handpicked professionals with a wealth of playing and recording experience.

All that talent wouldn’t mean a thing however, without great customer service. From finding that obscure Metallica piece to liaising with the venue on the best place to sit, we’ve got it covered. Actually, with well over 10 years experience, we’ve played in nearly every venue in South Wales, so we know the people and the spaces and we can help you picture how the quartet can fit into your special day.

A quartet can play so many different styles, you really couldn't ask for anything more. Add some modern style to your day.

It’s been a few years since my wedding, and whilst I couldn’t tell you what kind of flowers we had, the memories of the music are still vivid! Live music really transforms a gathering into an event, leaving a lasting memory for both you, and your guests. 

The beauty of a string quartet – four bowed stringed instruments – is that we produce a full sound which can ‘sustain’ the notes, with the acoustic control to be able to play as softly or as strongly as needed.  We can also play outdoors (in suitable weather) and our sound will still carry due to the nature of the instruments.

A good string quartet has the versatility to play any style you desire. Several styles convert very well into string quartet arrangements – jazz/swing, heavy metal, pop, ballads, and folk. We can also accompany the guests at churches for the hymn singing.

Over the years, we’ve built up a vast repertoire of music, classical, film and jazz – but primarily, modern, contemporary music. Please see our playlists for an up-to-date list of all we have. If you can’t see what you want, please get in touch to discuss your requirements.

Many of the arrangements I’ve written myself, some by players, and thanks to the Internet, many are bought from a number of trusted suppliers from across the world. Where we buy them in, we’ll review for quality, and where they don’t make the cut they’ll be re-worked to meet our high standards. Please bear in mind, whilst other quartets might have the same music as us, they will often not be to the same standard.
