Traditional Irish Music Structure Learning the structure of Traditional Irish Music is not difficult at all. Most tunes have 2 sections consisting of an "A" part and a "B" part, each having 8 bars of music. Each part in played twice so as the structure of the tune is "AABB". If the tune has 3 parts, then it is played "AABBCC". This is the general rule, although exceptions may exist. Each of these sections (or 8 bars), is made up of 4, 2 bar phrases...kind of like a question and answer. For example: "Are you sleeping, are you sleeping," - is the question of the first phrase "Brother John, Brother John," - is the answer of the first phrase "Morning bells are ringing, Morning bells are ringing," - is the question of the second phrase "Din dan don, Din dan don." - is the answer of the second phrase Here is an example using "Paddy Clancy's Jig: A three part jig would look like this, using "Arthur Daley's": Traditional Irish Music Time and Tempo Traditional Irish Music Modes and Scales
