The recordings in the archive are drawn from the TG4 programmes ‘Abair Amhrán’, ‘Amhrán is Ansa Liom’, and ‘Sean-Nós’, as well as their broadcasting of the singing competitions of the annual An tOireachtas festival. Virtually all singers of unaccompanied song in Irish, practicing at any point over the past 110 years, are included in the archive’s recordings. Representation of different regions of origin, age groups, and themes of song is highly diverse.
