Introduction: The Pulse of the Irish Session
Along with reels, jigs are the absolute heartbeat of traditional Irish music. Written in 6/8 time with its characteristic "dum-da-da dum-da-da" rolling pulse, the jig is designed to make feet tap and dancers move. But while a dance performance might rely on carefully rehearsed, unyielding tune selections, a real pub session is a living, breathing creature.
In a session, sets are constructed on the fly. As one tune finishes, a lead player must quickly launch into another, pivoting between keys and maintaining the momentum. To keep the music flowing without colliding into awkward fingerings or jarring chord shifts, the tradition relies on "glue tunes"—versatile jigs that work in dozens of different set combinations.
Using data from the **Trad Tune Explorer**, we analyzed thousands of tune sets and session recordings to map out the jig transition network quantitatively. By calculating **Degree Centrality** (the number of unique preceding and following tunes associated with each melody), we have identified the top 25 most versatile jigs in the traditional archive. These are the generalist tunes that can rescue a dying set, bridge distant key centers, and link players together across the globe.
What Makes a Jig Versatile?
To database engineers, versatility is a function of graph network centrality. But to traditional musicians, versatility is about flexibility and ease. A versatile jig must satisfy several crucial musical criteria:
- Outgoing Transitions (Exit Versatility): How easily a tune lets the session move forward. A jig with high exit versatility has a neutral ending note or scale position that resolves cleanly, allowing a player to slide into G major, D major, E Dorian, or A Dorian with equal comfort.
- Incoming Transitions (Entry Versatility): How easily other tunes can lead into it. Jigs with high entry versatility act as open doorways, resolving harmonic tension built up by more obscure or complex melodies.
- Modal Adaptability: Jigs that occupy harmonic middle grounds—such as G major, A Dorian, or D mixolydian—are highly versatile. They can easily modulate up or down a step (a common technique to add lift to a set) or pivot between relative majors and minors.
- Physical Ergonomics: A session glue tune must sit comfortably under the fingers. Simple, circular fingering patterns on the fiddle, tin whistle, concertina, and uilleann pipes allow musicians of all skill levels to join in effortlessly at high speeds.
The Studio vs. Session Paradox: The Locked Jigs
A common trap when building repertoire is confusing **popularity** (how often a tune is played) with **versatility** (how many contexts it can fit into).
Some jigs are incredibly popular due to a single legendary recording. For example, *The Jig of Slurs* (ranked #28 in versatility) is famous worldwide and played frequently (634 transitions). However, it has a total connected count of only 173 unique tunes. Why? Because it is often locked into rigid set structures (such as pairing it with *The Atholl Brose* or other Scottish-style sets). It behaves as a specialist rather than a generalist.
In contrast, look at **Out On The Ocean** (ranked #1 in versatility). It has a slightly lower absolute transition count than *The Kesh*, but it connects with a staggering **510 different tunes** (259 distinct next tunes and 251 distinct previous tunes). It is the ultimate connector, fitting seamlessly into almost any set, regardless of key or modal background. A versatile jig like *Out On The Ocean* is a structural bridge, whereas a popular but set-locked tune is a destination.

The 25 Most Versatile Irish Jigs
Here is the complete ranking of the 25 most versatile jigs in the traditional archive, compiled from transition network centrality on the Trad Tune Explorer.
1. Out On The Ocean
G MajorWhy it connects: Out On The Ocean is the undisputed champion of transition breadth. Though it has slightly fewer absolute transitions than The Kesh, it connects to a wider variety of unique tunes. Written in G major, its pentatonic-leaning, rolling melody sits perfectly on whistle, flute, and accordion. Its open-ended nature allows players to transition easily into D major, E Dorian, or A Dorian tunes.
Common Session Pairings: Most frequently leads into The Lilting Banshee (A Dorian, 5.2%), The Connaughtman's Rambles (E Dorian, 4.6%), or Tripping Up The Stairs (D major, 4.4%).
2. The Kesh Jig
G MajorWhy it connects: The Kesh is arguably the most famous jig in Irish music. Its simple, scalar G major structure makes it a universal session language—known by absolute beginners and seasoned veterans alike. Because it features a highly open, non-chromatic structure, it works as an easy entry point or resolution tune in almost any set.

Deep-Dive Feature Callouts
*Out On The Ocean* sits in G major, which shares a key signature with D major and E Dorian. Because it occupies the very center of this key family, it acts as a massive harmonic hub. Its melody is relatively simple, focusing on scalar steps and basic triads rather than complex jumps, which makes it extremely neutral. Guitarists can lay down solid, open drones under it, and backing players can take the set in almost any direction next. This harmonic neutrality is the secret to its massive 510 connected tunes score.
In almost every session in the world, if you play *The Kesh Jig*, you will follow it with *Morrison's*. Our database statistics show this transition is incredibly strong: **21.42% of the time** (281 times in sets), *The Kesh* leads directly into *Morrison's*. While this is a gorgeous pairing that resolves the G major lift into E Dorian momentum, it is a classic example of a strong set association. Thankfully, both tunes are so versatile that they also connect to hundreds of other tunes when players decide to break the mold.
The most surprising entry in the top 25 is **The Mouse In The Kitchen** (#21). Composed by Colin Farrell, it has rapidly climbed to become a session standard despite its modern origin. Another surprise is **Calliope House** (#5), which is written in E major. E major is traditionally considered a difficult key for whistles and flutes, yet the tune is so infectious and popular that it has successfully crossed over and developed 367 unique connections, proving that visual lift and danceability can overcome key signature biases.
A great session jig needs three features:
- Harmonic Neutrality: Supporting simple, open chords without forcing backing guitarists into frantic shifts.
- Ergonomic Fingering: Sitting comfortably under open holes on whistle and flute, avoiding complex cross-fingerings.
- Modal Anchoring: Starting and ending on common root notes (G, D, A) so players can easily slide in from other keys.
Frequently Asked Questions
What is a versatile jig?
A versatile jig is a traditional Irish tune in 6/8 time that demonstrates exceptional transition diversity. Rather than just being played frequently in a single static set, a versatile jig connects with a wide variety of different tunes (both preceding and following it) across different keys, modes, and sets.
How were these rankings calculated?
These rankings were calculated using network graph analysis on hundreds of thousands of recorded tune transitions from TheSession.org. Tunes were scored based on their 'degree centrality'—specifically, the number of distinct, unique preceding and following tunes associated with them in sets, rather than their absolute popularity count.
Are these the most popular jigs?
Not necessarily. Popularity counts how often a tune is played. Versatility measures how many different musical contexts a tune can fit into. For instance, some jigs are highly popular but are almost always played in the exact same set, whereas versatile jigs act as 'glue' and can be inserted into countless different combinations.
Why do some famous jigs rank lower?
Famous jigs like the Jig of Slurs are played often but have lower transition versatility because they are 'set-locked.' They are almost exclusively paired in a single famous combination, giving them high popularity but limited structural versatility in other sets.
How can I use versatile jigs when building session sets?
Versatile jigs are perfect 'bridge' or 'closer' tunes. If you want to transition between distant keys (e.g., from an E minor tune to a D major tune), inserting a versatile jig like Out On The Ocean or Morrison's provides a smooth, ergonomically satisfying bridge that most session players will instantly recognize and follow.
