    Chief Executive

    I was rubbish at the violin. I learned it so I could join the school orchestra and avoid the cadets. Then I realised that you needed a second instrument for most music colleges. I got accepted at the Royal Northern College of Music, the only one that didn’t need me to play the violin! Now, after a long convoluted journey, I’m here at Sinfonia Cymru. It’s such a joy working with young musicians who bring so much passion, energy and commitment to their work and who readily show the pleasure they get from making music together. This really is my perfect job – and I’ve had a lot to choose from over the last 40+ years! And they pay me to do it – imagine that.

  • Tammy Daly

    General Manager

    I grew up in North Devon and decided I wanted to play the french horn after seeing a wind quintet concert and thinking it looked pretty interesting! I was never brilliant at it but went on to music college in Cardiff and then Manchester where I soon realised my skills were better suited to the logistics and management side of music making. My first job was with Sinfonia Cymru as Orchestra Manager in 2008, before heading to the bright lights of London for 7 years and then returning to Sinfonia Cymru in 2017.  I love the variety of music and performances that this orchestra does, and the energy, excellence and positivity that all the wonderful musicians bring to each project. In my spare time I love live music of all different genres, and enjoy the great outdoors! 

  • Joseph Evans

    Concerts and Projects Manager

    I’ve always much preferred reading and talking about music to playing it (my trumpet has remained firmly in its case for at least two years now) and spent most of my time at university in Oxford and Cambridge obsessing over fugues. It’s great that I can continue to chat to people who love music and be part of planning exciting and diverse projects, working with such interesting musical personalities. I also grew up and had all of my first musical experiences in Cardiff, so I’m glad to be part of the musical culture here again. When I’m not thinking about music, I love to work my way through my increasingly large collection of recipe books, which is currently pushing fifty.

  • Simmy Singh

    Creative Associate

    I was born and raised in Llandybie where I was taught music by my wonderful mother. I headed for Chetham’s School of Music when I was 16 and went on to the RNCM after that and now enjoy a colourful and varied life as a freelance classical and crossover violinist. I am passionate about pushing boundaries and believe variety really is the spice of life and try to live true to that in my freelance career. From co-finding the Manchester Collective, to leading the Kaleidoscope Orchestra, recording strings for electronic producers and playing with some of the countries most exciting jazz artists with my quartet, Amika, I love every part of what I do. Until recently, when I reached the age cap, I was a long-standing member of Sinfonia Cymru and it really has helped shaped me into the musician I am today. I’m delighted to be able to continue the journey with this amazing family in my role as Creative Associate and to keep pushing, exploring and growing together, to give back all they have given me and to bring it all back home!

  • Heulwen Davies

    Marketing Consultant

    Shwmae, I’m Heulwen and through my business Llais Cymru, I’ve been leading the Marketing for Sinfonia Cymru since September 2021. I love music, I love singing, it relaxes me, makes me feel happy & alive, but I can’t for the life of me succeed to play an instrument! I tried the trumpet but couldn’t get any pleasant sounds out of it, my recorder and Irish whistle were banned from the family home, my violin teacher said my singing was much better, so I spent my violin lessons singing instead! In my 30’s I tried again with piano lessons alongside my 5 year old, I didn’t get anywhere! Instead, I’m focusing on my own strengths and enjoying the opportunity to share the stories of our amazing musicians and this fun orchestra that is Sinfonia Cymru. Musicians, I raise my hat to you!

  • Caroline Harris

    Development Consultant

    Music in all its forms has always been a huge part of my life, the more out there the better and crossing all genres. I still play (very amateur) clarinet, although it’s harder when you spend your life listening to the pros! Careerwise, I started life as a lawyer but not-so-secretly always wanted to work in the arts. In 2009 I made the move, working for six years at the Barbican Centre and four at Aurora Orchestra, and as a trustee of social drumming project Drum Works. It’s been everything I’ve hoped for – to “work” watching a rehearsal from inside an orchestra, or listening to world-class artists tuning up backstage? Nothing better! I believe passionately in creating opportunities in music and I’m thrilled to be contributing to that at Sinfonia Cymru.

    If you’d asked me in my early teens what I’d be getting up to as an adult, there is absolutely no chance I would even mention Classical Music! You’d be lucky to get the word ‘Music’ even, although, I was listening to all the bands of my day: SOAD, Papa Roach, Sum41, Nirvana, etc, while skateboarding, slightly hating school, gaming, all the standard teen stuff really. I started playing Viola when I was 9, I started enjoying music a lot from about 14, and fell completely in love with it by the age of 16, just in time to get all my grades together for applying to university. It is exactly our journey that gives us all a unique voice in this world, which brings me to the best part about being a musician – it is a journey never ends, and I look forward every day to what might be coming round the next corner…
