The Principality Only Boys Aloud Academi was established in 2011 to provide members of Only Boys Aloud showing particular musical promise access to expert and individual tuition more intensively than can be provided within the framework of general OBA rehearsals and performances. Aimed at the older boys in OBA aged between 16 and 19, there are 32 places available each year on this residential course. Selection is made following auditions. Whilst our open-access policy to OBA at a full-choir level is fundamental to the ethos of the scheme, it is vital that we manage the expectations of the boys in the choir. To this end, we feel that this process of selection for the Academi is not only desirable but creates an awareness of what is required to become a professional musician. During the week-long course the boys receive intensive training in all aspects of general musicianship, singing and performance. The Academi has produced a transformation in the boys who have attended over the last five years, and this in turn has had a hugely positive impact on the overall OBA choir.
