Concertina music centers around the concertina, a free-reed musical instrument in the bellows-driven family, distinct from the accordion by its smaller size and button layout parallel to the bellows movement. The genre encompasses a variety of styles depending on the specific type of instrument used: the 'English' concertina (chromatic and unisonoric) is often associated with Victorian parlor music and classical repertoire, while the 'Anglo' concertina (diatonic and bisonoric) is a staple of traditional Irish, English, and South African folk music. Characterized by its bright, piercing, yet warm tone, concertina music often features intricate melodic ornamentation, rhythmic drive for dances like jigs and reels, and rich harmonic accompaniment in song traditions. It is frequently a solo instrument but also thrives in ensembles, particularly in céilí bands and folk groups.

Uilleann pipes is both the name of a bellows-blown Irish bagpipe and a repertoire-centered performance practice within Irish traditional music. The instrument’s chanter, three drones, and up to three keyed regulators allow a uniquely lyrical, harmonically rich approach that differs markedly from other bagpipes. The style ranges from highly rhythmic dance tunes (reels, jigs, hornpipes, slip jigs) to deeply expressive slow airs that mirror the cadences of sean-nós singing. Technique centers on a “closed” fingering approach, leg-stopping the chanter to articulate phrasing, and idiomatic ornaments such as rolls, cuts, taps, and the hallmark uilleann “cran.” Because performers can accompany themselves with regulator chords, uilleann piping can sound simultaneously melodic and harmonized, making it a distinctive pillar of Irish traditional music and an expressive solo art in its own right.

Jig and reel are two of the most common dance-tune types in the Irish and Scottish traditional music repertoire. They are instrumental forms played for social dancing and session music, and they are defined primarily by their rhythms and phrase structures rather than by lyrics. Reels are in duple time (commonly notated in 4/4), with continuous streams of quavers/eighth notes and a strong, driving forward motion. Jigs are in compound time (most commonly 6/8 for single/double jigs and 9/8 for slip jigs), creating a lilting, bouncing feel. Typical tune forms are two strains of eight bars each (AABB), repeated and often strung into medleys. The core timbre is led by melody instruments such as fiddle, flute, tin whistle, uilleann pipes, accordion, and concertina, with accompaniment from guitar and bouzouki, and percussion from bodhrán. While rooted in the British Isles, jig and reel tunes have spread globally through diasporas and folk revivals, shaping the aesthetics of many fiddle traditions.
