If you\u2019ve ever sat in the corner of an Irish pub while a fiddle struck up a reel and the room seemed to hold its breath for half a second before the whole thing took flight \u2014 you already know what Irish traditional music is. You felt it before anyone could explain it.<\/p>\n
Irish traditional music \u2014 trad, as it\u2019s called at home \u2014 is Ireland\u2019s indigenous musical tradition. It\u2019s a living art form built on melody, improvisation and community, passed from player to player by ear for generations. The repertoire runs from blazing-fast reels and jigs to slow airs that could break your heart, and it\u2019s played on instruments like the fiddle, uilleann pipes, tin whistle, flute, concertina and bodhr\u00e1n that give the music its unmistakable sound.<\/p>\n
But here\u2019s what sets it apart from a museum piece: this isn\u2019t music preserved under glass. It\u2019s played every night of the week in pubs and kitchens and festival tents across Ireland and wherever Irish people have settled. New players are picking up instruments for the first time. New recordings are being made. The tradition is older than recorded history and younger than yesterday.<\/p>\n
At Radio Siamsa, we broadcast nothing but traditional Irish music, 24 hours a day. Our archive spans 1930s 78rpm recordings to albums released this year. This guide draws on that depth of listening \u2014 it\u2019s written for anyone who wants to understand what they\u2019re hearing, whether you\u2019re a lifelong fan, a curious newcomer, or someone in Boston or Sydney who just caught a tune on the radio and thought, \u201cWhat was that?\u201d<\/p>\n
Irish traditional music is the folk music native to Ireland. It developed over centuries as an oral tradition \u2014 learned by ear, not from sheet music \u2014 and it\u2019s characterised by its emphasis on melody, rhythmic drive, ornamentation, and the individual expression of each player.<\/p>\n
The \u201ctraditional\u201d label typically refers to the instrumental dance music: the jigs, reels, hornpipes, polkas and other tune types that form the core repertoire. But the broader tradition also includes sean-n\u00f3s singing (unaccompanied singing in Irish), songs in English, slow airs, and the harp music that was once the province of the Gaelic aristocracy.<\/p>\n
A few things make it distinctive. First, the melody is king. Unlike much Western folk music, there are no fixed chord progressions in Irish trad. The tune is the thing, and accompaniment \u2014 when it exists at all \u2014 serves the melody rather than driving it. Second, no two performances of a tune are the same. Musicians ornament, vary and subtly reshape tunes each time they play them. The melody is a framework, not a rigid score. Third, this is social music. The session \u2014 an informal gathering of musicians in a pub or kitchen \u2014 is the engine of the tradition. It\u2019s where tunes are shared, styles absorbed, and friendships formed over a shared love of the music.<\/p>\n
If you\u2019re new to trad, the first thing to get your ear around is the different tune types. Each has its own rhythm, feel and tempo. Once you can tell a jig from a reel, you\u2019re halfway to understanding what\u2019s happening in a session.<\/p>\n
The reel is the most common tune type in Irish music and the one most people picture when they think of trad. Reels are in 4\/4 time (four beats to the bar) and are usually played at a brisk tempo. The rhythm has an even, driving pulse \u2014 try saying \u201cdouble-decker, double-decker\u201d in time with the music and you\u2019ll feel it. Many of the most famous session tunes are reels, and a session will often feature long sets of them strung together.<\/p>\n
The reel actually came to Ireland from Scotland, probably in the 1700s. Early Irish music collections contain far more jigs than reels, but over time the reel came to dominate the repertoire. Today, many of the reels played in sessions are Scottish compositions, though Irish musicians have thoroughly made them their own.<\/p>\n
Jigs are the other half of the famous \u201cjigs and reels\u201d pairing, and they\u2019re arguably the older form in Irish music. The most common type is the double jig, played in 6\/8 time, which gives it that distinctive bouncing, lilting feel. An old trick for recognising a jig: say \u201crashers and sausages, rashers and sausages\u201d in time with the music. If it fits, it\u2019s a jig.<\/p>\n
There are also single jigs (a simpler rhythm, sometimes in 6\/8 or 12\/8) and slip jigs, which are in the unusual time signature of 9\/8. Slip jigs have a graceful, flowing quality quite different from the bouncier double jig \u2014 they\u2019re sometimes described as the most elegant of all Irish dance forms.<\/p>\n
Hornpipes are in 4\/4 time like reels, but they\u2019re played slower and with a distinctive dotted or \u201cswung\u201d rhythm that gives them a heavier, more deliberate feel. Where a reel flies, a hornpipe struts. They\u2019re associated with a slower, more precise style of step dancing. The hornpipe came to Ireland from England, but like the reel, it was absorbed into the tradition and made thoroughly Irish.<\/p>\n
Polkas are particularly associated with the Sliabh Luachra region of Kerry and Cork. They\u2019re in 2\/4 time, fast and bouncy, with a strong dance rhythm. Slides are related to polkas but in 12\/8 time, giving them a smoother, more rolling feel. If you hear music that sounds like it belongs in a Kerry kitchen with flagstones under the dancers\u2019 feet, you\u2019re probably hearing polkas or slides.<\/p>\n
Not all trad is fast. Slow airs are the contemplative side of the tradition \u2014 instrumental versions of songs, played with great freedom and expression. There\u2019s no fixed tempo; the player breathes with the melody, stretching and compressing phrases as the mood takes them. A good slow air on uilleann pipes or fiddle is one of the most emotionally powerful things in all of Irish music. Many airs are drawn from sean-n\u00f3s songs, and hearing the instrumental and vocal versions side by side is one of the great pleasures of deep listening.<\/p>\n
The tradition also includes mazurkas (from Poland, via the Continent, absorbed mainly in Donegal and parts of the west), set dances (specific tunes tied to specific dance steps), marches, waltzes and barn dances. The repertoire is broader than many people realise, and exploring beyond the jigs-and-reels basics is where the real discovery begins.<\/p>\n
Irish trad is played on acoustic instruments, mostly melody instruments. This is music built on the single line \u2014 one tune, one voice at a time \u2014 and the instruments reflect that.<\/p>\n
For a deeper dive into each instrument, see our full guide to Irish Traditional Music Instruments<\/a><\/p>\n The fiddle is the most widely played instrument in Irish traditional music. It\u2019s identical to a violin \u2014 the difference is entirely in the playing style. Irish fiddlers hold the instrument in various ways (some on the shoulder, some tucked under the arm), and the bowing and ornamentation are completely different from classical technique.<\/p>\n What makes the fiddle central to trad is its expressiveness and its ability to adapt to wildly different regional styles. The Sligo style is flowing and ornamented, influenced by the recordings of Michael Coleman in 1920s New York. Donegal fiddling is rhythmically fierce, shaped by the Scottish tradition. Clare playing is spare and precise. Kerry fiddling, in the Sliabh Luachra tradition, is rhythmic and dance-driven. The same instrument, the same tunes \u2014 but listen to a Sligo fiddler and a Donegal fiddler play the same reel and you\u2019ll hear two different musical worlds.<\/p>\n The uilleann pipes are Ireland\u2019s most distinctive instrument and arguably its most complex. Unlike Scottish bagpipes, which are blown by mouth, uilleann pipes (the name comes from the Irish word for \u201celbow\u201d) are powered by a bellows held under the arm. They\u2019re quieter and more nuanced than their Scottish cousins, with a range of about two octaves and the ability to play staccato as well as legato.<\/p>\n A full set of uilleann pipes includes a chanter (the melody pipe), three drones and three regulators that can play chords. In the hands of a master \u2014 S\u00e9amus Ennis, Liam O\u2019Flynn, Paddy Keenan, Paddy Moloney \u2014 the pipes can do things no other instrument can. They can whisper and roar, play slow airs of devastating beauty and tear through reels at blistering speed. They\u2019re difficult to learn (it\u2019s said to take seven years of learning, seven years of practising and seven years of playing before you master them), but the sound is worth every one of those years.<\/p>\n The tin whistle \u2014 also called the penny whistle \u2014 is the most accessible instrument in Irish music. It\u2019s cheap, portable, and the basics can be learned in an afternoon. But don\u2019t mistake simplicity for limitation. In the hands of a skilled player like Mary Bergin or Paddy Moloney, the tin whistle is capable of astonishing speed and delicacy. It\u2019s the instrument most Irish schoolchildren learn first, and for many people it\u2019s the gateway into the tradition.<\/p>\n The Irish flute is not the silver concert flute you see in an orchestra. It\u2019s a simple-system wooden flute, the kind that classical musicians abandoned in the mid-1800s when the modern Boehm flute was developed. Irish musicians adopted these cast-off instruments and never looked back. The wooden flute has a warm, breathy tone quite different from its metal successor, and it suits the ornamentation and phrasing of Irish music perfectly. Matt Molloy of The Chieftains is perhaps the best-known Irish flute player.<\/p>\n The bodhr\u00e1n (pronounced roughly \u201cbowrawn\u201d) is a frame drum made of a wooden hoop with goatskin stretched over one side. It\u2019s played with a small wooden stick called a tipper, while the other hand presses the back of the skin to vary the pitch and tone. A good bodhr\u00e1n player locks in with the rhythm of the tune and drives the session forward without overwhelming the melody instruments. It\u2019s a relatively modern addition to the trad ensemble \u2014 its current style of playing only developed in the latter half of the 20th century.<\/p>\n The button accordion and concertina arrived in Ireland in the late 19th century and quickly became staples of the tradition. The concertina is particularly associated with County Clare. The tenor banjo came over from America in the 1920s and was adapted for melody playing rather than the chord-strumming it was used for in jazz. The bouzouki was introduced from Greece in the 1960s by Johnny Moynihan and later popularised by D\u00f3nal Lunny; it\u2019s now one of the primary accompaniment instruments in trad, though it wasn\u2019t part of the tradition even fifty years ago.<\/p>\n This is one of the things that makes trad alive rather than frozen: new instruments keep arriving, musicians keep experimenting, and the tradition absorbs what works.<\/p>\n If you want to understand Irish traditional music, you need to understand the session. A session (or seisi\u00fan) is an informal gathering of musicians, typically in a pub, where they sit in a rough circle and play tunes together. There\u2019s no audience in the formal sense \u2014 anyone in the pub can listen, and the musicians play as much for themselves and each other as for anyone else.<\/p>\n Sessions are governed by unwritten rules that newcomers sometimes find mysterious. Generally, one or two musicians will lead by starting a tune, and others join in as they recognise it. Tunes are usually played in sets of two or three, grouped by type (a set of reels, a set of jigs). The pace is set by the lead player, and it\u2019s bad form to play louder than everyone else or to start a tune nobody knows.<\/p>\n The session is the social heart of the tradition. It\u2019s where young players learn tunes, where musicians from different regions exchange styles, and where the repertoire stays alive and evolving. Sessions happen every night of the week in towns and cities across Ireland, and in Irish communities around the world \u2014 from New York to Sydney, Tokyo to Buenos Aires.<\/p>\n Read our full guide to the trad session, including session etiquette for beginners<\/a><\/p>\n One of the richest things about Irish traditional music is its regional diversity. Ireland is a small island, but the music changes noticeably from county to county, shaped by geography, local tradition, and the influence of particular musicians.<\/p>\n The Sligo style is perhaps the most widely known, thanks largely to Michael Coleman. Coleman emigrated to New York in 1914 and made a series of recordings in the 1920s and 30s that electrified musicians back home and around the world. His playing was virtuosic, highly ornamented and rhythmically fluid. The Sligo style he popularised emphasises long, flowing bowing and elaborate rolls and triplets. James Morrison, another Sligo emigrant in New York, was equally influential.<\/p>\n County Clare is the heartland of Irish trad. The Clare style tends to be more understated than Sligo \u2014 less ornamentation, more emphasis on rhythm and the inherent shape of the tune. It\u2019s the style of playing you\u2019re most likely to hear in a session today. Clare is also the spiritual home of the concertina in Irish music, with players like Mrs Crotty and Noel Hill defining the sound. The Willie Clancy Summer School, held in Miltown Malbay each July, is the largest traditional music education event in the world.<\/p>\n Donegal\u2019s fiddle tradition is distinct from the rest of Ireland, with strong Scottish influences. The playing is rhythmically intense, with aggressive bowing and a driving energy that reflects the county\u2019s connections to Scotland. Donegal fiddlers also play a wider range of tune types, including highlands and mazurkas that are rare elsewhere. The late Tommy Peoples and Mairead N\u00ed Mhaonaigh of Altan are among the best-known Donegal fiddlers.<\/p>\n The Sliabh Luachra region, straddling the borders of Kerry, Cork and Limerick, has its own fierce musical identity. The music is deeply tied to dance \u2014 polkas and slides dominate the repertoire, and the playing is rhythmic, percussive and endlessly propulsive. P\u00e1draig O\u2019Keeffe, Denis Murphy and Julia Clifford are the towering figures of the tradition. It\u2019s some of the most exciting music in all of Ireland.<\/p>\n Explore our full guide to the regional styles of Irish traditional music<\/a><\/p>\n Irish traditional music doesn\u2019t have composers in the classical sense. Instead, it has players whose individual brilliance, recordings and influence have shaped how the music sounds today. Here are some of the figures you\u2019ll hear mentioned most often.<\/p>\n Michael Coleman (1891\u20131945)<\/strong> \u2014 The Sligo fiddler whose 1920s New York recordings essentially created the modern tradition. His virtuosity and rhythmic freedom remain the benchmark.<\/p>\n S\u00e9amus Ennis (1919\u20131982)<\/strong> \u2014 Piper, collector and broadcaster. Ennis was a towering figure: a supreme piper who also spent years collecting tunes and songs across Ireland for the Irish Folklore Commission and the BBC.<\/p>\n Paddy Moloney (1938\u20132021)<\/strong> \u2014 Founder of The Chieftains, the group that more than any other brought Irish traditional music to international audiences. Moloney\u2019s uilleann piping and tin whistle playing defined the sound of Irish music for millions.<\/p>\n Planxty and The Bothy Band<\/strong> \u2014 In the 1970s, these two groups revolutionised the trad scene. Planxty (Christy Moore, D\u00f3nal Lunny, Andy Irvine, Liam O\u2019Flynn) brought a contemporary sensibility to the music. The Bothy Band (Matt Molloy, D\u00f3nal Lunny, Paddy Glackin, Tr\u00edona N\u00ed Dhomhnaill and others) played with a ferocious energy that still sounds thrilling today.<\/p>\n Martin Hayes<\/strong> \u2014 The East Clare fiddler whose slow, meditative style has redefined what trad can be. His playing is deeply rooted in the tradition but sounds like nothing else. His group The Gloaming brought trad into conversation with contemporary art music.<\/p>\n Sharon Shannon<\/strong> \u2014 The button accordion player from Clare whose debut album became one of the best-selling traditional music records in Irish history. Shannon\u2019s joyful playing and willingness to experiment with other genres \u2014 reggae, Cajun, rock \u2014 won trad a whole new audience.<\/p>\n See our full guide to the great Irish traditional musicians<\/a><\/p>\n Sean-n\u00f3s (\u201cin the old style\u201d) is the ancient, unaccompanied singing tradition of Ireland. It\u2019s performed solo, almost always in Irish, and it\u2019s one of the most haunting sounds in all of European music. The singer sits still, often with eyes closed, and delivers a melody that is heavily ornamented \u2014 the vocal equivalent of the rolls and cuts that instrumentalists use. Each singer has their own style of ornamentation, and no two performances of the same song are identical.<\/p>\n Sean-n\u00f3s is most strongly associated with the Gaeltacht areas \u2014 the Irish-speaking regions of Connemara, West Kerry, and Ring in County Waterford \u2014 each of which has its own distinct singing style. In Connemara, the singing tends to be highly ornamented and rhythmically free. In Munster, it\u2019s more structured and melodically driven.<\/p>\n This is music that rewards patience. It doesn\u2019t grab you in the way a blazing set of reels does. But if you give it time, sean-n\u00f3s singing opens up emotional depths that no other form of Irish music quite reaches.<\/p>\n Ornamentation is what gives Irish traditional music its texture and personality. Where classical musicians play the notes as written, trad musicians add small, rapid decorative notes around the main melody. These ornaments aren\u2019t random \u2014 they follow conventions that vary by instrument and region \u2014 but they\u2019re applied spontaneously, which is why the same tune sounds different every time it\u2019s played.<\/p>\n The main ornamental techniques include cuts (a brief grace note above the main note), taps or strikes (a grace note below), rolls (a combination of cut and tap that creates a rapid three-note decoration), slides (approaching a note from below), and crans (a technique specific to the uilleann pipes involving rapid articulations on a single note).<\/p>\n Good ornamentation is subtle. The mark of a skilled player isn\u2019t how many ornaments they use, but how tastefully they deploy them. A less-is-more approach is almost always preferable, especially for players learning the tradition. As the saying goes, the tune comes first \u2014 the ornaments serve it, not the other way around.<\/p>\n Read our detailed guide to ornamentation in Irish music<\/a><\/p>\n Ireland\u2019s musical tradition stretches back further than written records. Archaeological evidence of musical instruments \u2014 including a set of wooden pipes from around 2000 BC found in County Wicklow \u2014 suggests that music has been part of life on this island for at least four thousand years.<\/p>\n The harp dominated Irish music from at least the 10th century through to the 17th, closely tied to the Gaelic aristocracy. Harpers were prestigious figures, and the tradition produced virtuosos like Turlough O\u2019Carolan (1670\u20131738), the blind harper and composer whose work blended Irish and Baroque traditions and whose tunes are still played today.<\/p>\n The decline of the Gaelic order and the devastation of the Great Famine (1845\u20131852) reshaped Irish music. The harping tradition largely died out. But the dance music tradition \u2014 the jigs, reels and hornpipes played on fiddles, flutes and pipes \u2014 survived among the rural poor and was carried to America, Britain and Australia by emigrants.<\/p>\n In the early 20th century, Irish musicians in New York \u2014 Coleman, Morrison, John McKenna \u2014 made recordings that captured the tradition on 78rpm discs and sent it back across the Atlantic. These recordings were transformative. For the first time, musicians in remote parts of Ireland could hear virtuoso playing from Sligo or Clare, and it raised the bar for everyone.<\/p>\n The folk revival of the 1960s brought Irish music to broader attention. The Clancy Brothers and Tommy Makem became international stars. Then came The Chieftains, Planxty, The Bothy Band, De Dannan and Clannad in the 1970s, followed by Stockton\u2019s Wing, Altan, Dervish, L\u00fanasa and many more. By the 1990s, the success of Riverdance made Irish music and dance a global phenomenon.<\/p>\n Today, the tradition is in robust health. More people play Irish traditional music now than at any time in history. Organisations like Comhaltas Ceolt\u00f3ir\u00ed \u00c9ireann promote the music worldwide. The annual Fleadh Cheoil na h\u00c9ireann draws hundreds of thousands. And digital broadcasting means that anyone, anywhere, can tune in to the tradition \u2014 which is exactly why Radio Siamsa exists.<\/p>\n Explore our full history of Irish traditional music<\/a><\/p>\n There has never been a better time to discover Irish traditional music. The recordings available span over a century, from Michael Coleman\u2019s crackling 78s to pristine modern studio albums. Live sessions happen nightly. Festivals run all summer. And online, a few dedicated stations keep the music playing around the clock.<\/p>\n If you\u2019re just beginning to explore, here\u2019s where to start:<\/p>\n See our full guide to listening to Irish music online, including how to listen on Alexa and smart speakers<\/a><\/p>\n There are practical reasons to care about Irish traditional music. It influenced country, bluegrass and roots music in America. It\u2019s the basis for the global Celtic music phenomenon. It\u2019s one of the most vibrant folk music traditions surviving anywhere in the Western world.<\/p>\n But the real reason it matters is harder to pin down. It\u2019s in the way a slow air can stop a noisy pub dead. It\u2019s in the feeling of recognition when you hear a tune your grandmother hummed. It\u2019s in the way a session in Tokyo or Toronto can make an emigrant feel, for three hours on a Tuesday night, like they\u2019re home.<\/p>\n Irish traditional music is a thread that connects the Ireland of stone forts and round towers to the Ireland of tech campuses and motorways. It carries memory. It creates community. And it sounds magnificent.<\/p>\n At Radio Siamsa, we exist to keep that thread unbroken. Tune in, and hear it for yourself.<\/p>\n Irish traditional music is the specific folk music tradition of Ireland. \u201cCeltic music\u201d is a broader, more commercial term that groups together the traditional music of Ireland, Scotland, Wales, Brittany, Galicia and other Celtic nations. Most trad musicians in Ireland prefer the term \u201cIrish traditional music\u201d or simply \u201ctrad\u201d \u2014 it\u2019s more precise and respects the unique character of the Irish tradition rather than lumping it in with other, quite different, musical cultures.<\/p>\n The core melody instruments are the fiddle, tin whistle, wooden flute, uilleann pipes, concertina and button accordion. The bodhr\u00e1n provides percussion. Accompaniment instruments include the guitar (often in DADGAD tuning), bouzouki and piano. The harp<\/a>, though Ireland\u2019s national symbol, is less common in session settings but has a rich tradition of its own.<\/p>\n A session (seisi\u00fan) is an informal gathering of musicians who play traditional Irish music together, typically in a pub. Musicians sit in a circle, take turns leading tunes, and play in unison. Sessions are the social heart of the tradition and happen regularly in towns across Ireland and in Irish communities worldwide.<\/p>\n A reel is in 4\/4 time with an even, driving rhythm (think \u201cdouble-decker, double-decker\u201d). A jig is in 6\/8 time with a bouncing, lilting rhythm (think \u201crashers and sausages, rashers and sausages\u201d). Reels tend to feel fast and flowing; jigs feel bouncier and more dance-like.<\/p>\n More popular than ever. More people play Irish traditional music today than at any point in history. The annual Fleadh Cheoil na h\u00c9ireann attracts hundreds of thousands of visitors. Sessions run nightly across Ireland and in cities worldwide. And dedicated stations like Radio Siamsa make it accessible to anyone with an internet connection.<\/p>\n Radio Siamsa streams traditional Irish music 24\/7 at siamsa.ie. You can also listen via smart speakers (ask Alexa to play Radio Siamsa), through the TuneIn app, or directly on our website. Other sources include RT\u00c9 Raidi\u00f3 na Gaeltachta and Ceol FM.<\/p>\n Sean-n\u00f3s (\u201cin the old style\u201d) is the traditional unaccompanied singing of Ireland, performed solo, usually in the Irish language. It\u2019s characterised by elaborate vocal ornamentation and rhythmic freedom. Each singer develops their own distinctive style of decoration, making every performance unique.<\/p>\n Sessions take place in pubs across Ireland \u2014 particularly in the west and in Dublin. Outside Ireland, cities with significant Irish communities (New York, Boston, Chicago, London, Sydney) have regular sessions. The website TheSession.org has a global session finder. Major festivals include the Fleadh Cheoil, the Willie Clancy Summer School, and numerous local fleadhanna throughout Ireland.<\/p>\nThe Fiddle<\/h3>\n
