The Open A cappella Competition

The UK's only fully open a cappella competition


What is The Open A cappella Competition?

The Open A Cappella Competition is an annual competition designed to showcase collegiate and community a cappella groups across the UK. Our inaugural competition ran in 2020 with 10 highly acclaimed groups. Since then, we’ve run the OAC four times in total – all for the love of a cappella.

The competition usually lasts 2-3 hours, packed full of excitement and fun, with each group presenting their own musical arrangements and choreography during their 10 minute time slot.

If you’d like to watch our most recent 2024 competition – head over to our home page to rewatch it on youtube.
