Editing Uilleann pipes (section)

===Full set===
[[Image:UilleannPipes.jpg|thumb|right|alt=A full set of Uillean pipes.|Full set]]A '''full set''', as the name implies, is a complete set of uilleann pipes. This would be a half set with the addition of three regulators. These are three closed pipes, similar to the chanter, held in the stock. Like the drones, they are usually given the terms tenor, baritone, and bass, from smallest to largest. A regulator uses keys (five on the tenor and four on both baritone and bass) to accompany the melody of the chanter; these keys are arranged in rows to give limited two-note "chords" or, alternatively, single notes for emphasis on phrases or specific notes. The notes of the regulators, from highest to lowest (given a nominal pitch of D) are as follows: tenor: C, B, A, G, F{{music|#}}; baritone: A, G, F{{music|#}}, D; bass: C, B, A, G. The tenor and baritone regulators fit into the front face of the stock, on top of the drones; the bass regulator is attached to the side of the stock (furthest from the piper), and is of complex construction.

Another method of using the regulators is to play what are referred to as "hand chords": when the melody (usually in a slower piece of music such as an [[Sean-nós singing|air]]) is being played on the chanter exclusively with the left hand, the right hand will be free to create more complex chords, using all three regulators at once if so desired. Many airs end a section on a G or A in the first octave, at which point a piper will often play one of these hand chords for dramatic effect.
