Fleadh Ceol na hEireann aka the All Ireland

The Fleadh Cheoil Na hEireann is the annual All Ireland championship. In the Fleadh there are competitions for music, song, dance and every instrument at every age group. There is of course a bodhrán competition. To qualify for the All Ireland, a competitor must win through the county and provincial stages. Because every competitor at the All Ireland is either a regional champion or runner up, the standard is exceptionally high.

As well as Irish counties and provinces, representation is accepted from CCE members around the world. Outside of Ireland the branches are Britain, USA & Canada or Rest of the world. The All Ireland is in effect the world championship. For bodhrán at senior level (18+) the player is accompanied by a melody player of their choosing. They must play 4 tunes of their choosing, each must be of a different rhythmic type, eg, a jig, a reel, a hornpipe & a polka. Each tune is played twice only. A single ajudicator makes a decision regarding who the winner is. Quite often this person is not a bodhrán player. If the standard is not deemed to be sufficiently high, an ajudicator may recommend that none of the competitors may progress. This is rare.
