premiere taking part

yn un rhith – a choir still

On Friday 22 May 2020, yn un rhith was premièred in a joint virtual choir performance by Côr ABC and Côr Dinas. Here is the video!

If you have an SSA or SATB choir, we will be updating this site in the next few days so that you can access everything you need (except for a video editor!) to produce your own virtual choir performance of yn un rhith, including the musical score, relevant warm-ups, videos to learn and record with, and the accompaniment track, so do sign up on the ‘get updates’ page if you are interested.

Here, also, are the links to the performances by each of the choirs.

the project

Aberystwyth based mixed choir, Côr ABC, and the London Welsh women’s choir, Côr Dinas, have been working together on a virtual choir project to produce the first performance of a new piece written during the first few weeks of lockdown by composer, Andrew Cusworth.

Weekly choral rehearsals had come to an abrupt end back in March as COVID-19 spread around the world and governments introduced restrictions on all aspects of daily life. In response to this, Côr ABC and Côr Dinas began to meet and rehearse virtually, enabling their members not only to continue to sing and make music, but also to maintain their social connections. These virtual rehearsals proved to be an inspiration for a new piece and a virtual choir project.

After one of Côr ABC’s rehearsals, choir member and crowned bard, Dafydd John Pritchard, wrote an englyn about the experience and posted it on Twitter. Fellow choir member and conductor of Côr Dinas, Andrew Cusworth, saw the poem and set it to music for both choirs to sing together virtually.

Speaking about his new piece, yn un rhith, Andrew said: “The piece, based on Dafydd’s poem, sings of how, albeit set apart by events, we are still united in our aims, as a community, in singing – of how we are still a choir.”

Over recent weeks, members of both choirs have been filming themselves singing the piece, and all those individual videos are now being edited together to create a virtual choir performance by Robert Russell, who also accompanies the choirs in the performance.

Describing the aim of the project, Gwennan Williams, conductor of Côr ABC, said: “Our hope, as a team who put the project together, was to create an enjoyable experience for our members, and something that we can all look back on, at some point in the future, as a reminder of something positive to come out of difficult times.”

The first performance of yn un rhith by the combined choir of Côr ABC and Côr Dinas will shortly be released in a YouTube première event. The choirs will also perform, separately, mixed choir and upper voices versions of the piece.

the words

The words of this piece are those of an englyn by crowned bard Dafydd John Pritchard, written after first attending one of Côr ABC’s virtual rehearsals. Here is Dafydd reading it.

Er o bell, roedd herio byd heno’n gân 
     yn y gwaed, yn fywyd, 
  pob tôn yn fonllef hefyd, 
  yn un rhith, yn gôr o hyd.

Here is his adaptation of the words into English.

Yes, from a distance, but we fought back tonight, 
      our song being lifeblood,
   every note we sang, a cry,
   virtually one, a choir still.

One of the many reasons that we sing in choirs is for the positive effect it has on our mental health. Beyond the well-known benefits of group singing, choirs are micro-communities united by the urge to make music; choirs are made up of often diverse people who share experiences, support each other, and enjoy the social side of choral music as well as the singing itself. During the lock-down, choirs have had to find new ways of continuing to gather not only for musical reasons but for social and community ones, and as a means of raising the spirits of their members, staying in touch, and looking out for one another. With all of these positive things and the community-driven background to the project in mind, we would like to draw attention to the importance of music in our lives, and during what is Mental Health Awareness Week in the UK, in our human wellbeing.

So, if you have enjoyed finding out about, listening to or participating in our project, and if you are in a position to do so, why not consider making a donation to a mental health or musical charity near you.
