The following distinction is primarily observed in modern competitive Irish dance and should not be confused with the general notion of how the jigs are played and classified among traditional Irish musicians.
Light jigs A light jig is the second-fastest of all jigs. The performer's feet rarely leave the ground for long, as the step is fast, typically performed at a speed around 116 at
feiseanna. There are several light jig steps, varying with each dance school, but the rising step, or the rise and grind, is standard in almost all light jigs. The right side version of the rising step is performed by putting weight on the left foot, lifting the right foot off the ground then hopping on the left foot once. Hop on the left foot again, bringing the right foot back behind the left foot and then shift the weight onto the right foot, leaving the left foot in the air. Dancers use the phrase "hop, hop back" for these three movements, and there is a slight pause between the hop, and hop back. The next movement is a hop on the right foot. Then shift the weight, left-right-left-right. The phrase for this whole movement is: "hop, hop back, hop back 2-3." To do the step on the left foot, reverse the left and right directions.
Slip jigs Slip jigs are in time. Because of the longer measures, they are longer than the
reel and the light jig, with the same number of bars to the music. The dance is performed high on the toes, and is often considered the "ballet of Irish dance" because of its graceful movements that seem to slip the performers across the floor. Slip jigs are performed at a speed of 113 bpm at feiseanna.
Single and double jigs , a double jig Single jigs should not be confused with
slides; they are the least common of the jigs, performed in ghillies, in a or less commonly a time. Musically, the single jig tends to follow the pattern of a quarter note followed by an eighth note (twice per bar), whereas the pattern for the double jig is three eighth notes twice per bar.
Hop jigs Hop jigs are the fastest of all jigs next to light jigs, but the term
hop jig causes some confusion, as some people use it for a single jig, while others use this term to refer to a tune in time. Among the latter, some do not distinguish it from a slip jig, while some reserve the term to a slip jig variant that has special characteristics, in particular an emphasis on
quarter note–
eighth note pairs.
Treble jigs Treble jigs (also called the hard or heavy jig) are performed in hard shoes, and also to a time metre. They are characterized by stomps, trebles, and clicks. Many set dances are performed in treble jig time, a few being Drunken Gauger, Blackthorn Stick, The Three Sea Captains, and St Patrick's Day. Two types of treble jigs are performed at feiseanna: the traditional and non-traditional (slow) treble jigs. Beginners will do a treble jig at traditional speed (92 bpm), while more advanced dancers will dance the non-traditional (slow) treble jig at 72 bpm. ==Straight and sand jigs==
