Introduction: The Flowing Lilt of the Slip Jig
In traditional music, the slip jig holds a unique, elegant status. While standard double jigs are written in 6/8 time with a bouncy two-beat pulse per bar, the slip jig is written in 9/8 time, giving it three strong beats per bar. Its flowing, rolling lilt makes it highly distinct, historically associated with graceful step dancing. Standards like The Butterfly, The Kid on the Mountain, and The Rocky Road to Dublin are staples of traditional sessions worldwide.
Yet slip jigs represent a relatively small portion of the active session repertoire. Most sessions rely heavily on a small handful of very popular slip jigs. Beyond these common standards lie several highly recorded, beautiful melodies that are rarely called by session players.
Using the quantitative data of the **Trad Tune Explorer**, we analyzed commercial album tracks, user bookmarks, and session set frequencies to identify 3 outstanding, underrated slip jigs. These melodies offer exceptional syncopations, beautiful modal changes, and satisfying fingerings, making them prime candidates for session players looking to diversify their sets.
Our analytics engine calculates a **Hidden Gem Score** by comparing two opposing signals: professional studio adoption (quality signal) against live session set frequency (exposure signal). A high score indicates a tune of proven aesthetic value that remains underplayed.
- Top Hidden Gem: The Rainy Day (22 commercial recordings, 1 session set, 1 bookmark)
- Shetland Classic: Papa Stour Sword Dance (13 commercial recordings, 2 session sets, 0 bookmarks)
- Connacht Masterpiece: Cuaichin Ghleann Neifin (13 commercial recordings, 1 session set, 1 bookmark)

What is a Hidden Gem?
In plain terms, a "Hidden Gem" is a tune that shows a significant imbalance between its professional recording history and its modern community adoption. These are not obscure, unplayable tunes scribbled in the margins of a dusty 19th-century manuscript. Rather, they are high-quality, fully realized melodies that have been chosen, arranged, and recorded by professional recording artists on commercial albums.
A tune becomes a hidden gem when it has been vetted and performed by elite musicians, yet fails to transition into the common repertoire of the casual session circle. It represents an untapped resource—a melody of proven aesthetic quality that is ripe for rediscovery and study by session musicians looking to expand their repertoire.
How We Measured This
Rather than relying on subjective opinions about which slip jigs are "underrated," this analysis uses the quantitative analytics engine of the **Trad Tune Explorer**. We calculated a composite score for each tune by comparing two opposing signals:
- The Quality Signal (Commercial Footprint): This is derived from the total count of commercial album tracks, the number of distinct artists who have recorded the tune, and its appearance in historical and modern tunebooks.
- The Exposure Signal (Community Adoption): This is measured by the number of active user bookmarks on the site and the frequency of the tune's appearance in community-submitted session sets.
By subtracting the exposure signal from the quality signal, we identify tunes with a massive gap between professional appreciation and community practice. A high hidden gem score highlights tunes that have been recorded dozens of times but are played in almost zero sessions.

Top 3 Hidden Gem Slip Jigs
Below is the complete dataset of the 3 hidden gem slip jigs identified by the Trad Tune Explorer, ordered by their Hidden Gem Score.
1. Rainy Day, The
EminorStatistical Summary: Recorded 22 times by 20 artists, but appears in only 1 bookmarks and 1 session sets. Evidence Level: strong.
Analysis: While most traditional musicians know the famous reel called The Rainy Day, the slip jig of the same name is a much rarer treasure. It is a winding, modal melody in E minor (usually played as E dorian/aeolian) that carries a haunting, atmospheric quality. The tune boasts a massive commercial presence with 22 recordings by 20 distinct artists, including a legendary arrangement by the Kilfenora Céilí Band on their album Set on Stone.
Despite this substantial commercial backing, it has virtually zero footprint in the community, with only a single recorded session set and a single user bookmark. Its modal shifts and slightly less intuitive leaps explain its absence from casual sessions, but it is an incredibly rewarding piece for whistle and fiddle players looking for a dark, expressive slip jig.
2. Papa Stour Sword Dance
GmajorStatistical Summary: Recorded 13 times by 11 artists, but appears in only 0 bookmarks and 2 session sets. Evidence Level: medium.
Analysis: Hailing from the remote island of Papa Stour in Shetland, this tune accompanies a historic, dramatic sword dance. It is a driving G major melody that combines a march-like punch with the flowing 9/8 rhythm of a slip jig. Shetland fiddle royalty Aly Bain and Swedish multi-instrumentalist Ale Möller recorded a canonical version of this tune on their album Fully Rigged. It has also been interpreted by English folk-rockers Fairport Convention and the Boys of the Lough.
As a Shetland tune, it is geographically isolated from mainstream traditional session circles. It is often played at a slower, more deliberate tempo suited for dancing, which has limited its adoption in high-speed pub sessions. However, its strong, rhythmic pulse makes it instantly accessible and a great set starter.
3. Cuaichin Ghleann Neifin
GmajorStatistical Summary: Recorded 13 times by 10 artists, but appears in only 1 bookmarks and 1 session sets. Evidence Level: medium.
Analysis: Translating to "The Little Cuckoo of Glen Nefin," this beautiful Connacht melody was recorded by accordion master Joe Burke on The Tailor's Choice. It is also highly recognized in Gaelic song archives. The tune is a lyrical G major slip jig characterized by sweeping, elegant arpeggios that mimic the song of the cuckoo.
Because it is frequently played as a song air, many session musicians overlook it as a dance tune. Its song-like structure requires a lighter, more expressive phrasing than standard session fare, meaning it can get lost in a loud pub setting. Nonetheless, when played with care, it makes a breathtaking contrast to faster reels.
Common Patterns in the Data
Analyzing these 3 hidden gems highlights several characteristics of the slip jig archive:
- Minor Key Scarcity: Winding minor-key tunes like The Rainy Day require delicate phrasing and are far less common than major-key session staples, leading to lower live exposure.
- Regional and Dance Style Separation: Tunes like Papa Stour Sword Dance originate outside the standard Irish repertoire (Shetland/Scottish traditions), making them less likely to cross over into general traditional session lists.
- Air and Song Origins: Melodies like Cuaichin Ghleann Neifin have strong histories as lyrical vocal songs, meaning players often treat them as slow listening pieces rather than session slip jigs.
Why Hidden Gems Matter
Expanding your session list with underrated slip jigs is a great way to introduce variety. Adding modal shifts and regional flavors from Shetland or Connacht brings fresh interest and textures to a session circle, encouraging other players to explore the vast corners of the tradition.
Frequently Asked Questions
What is a hidden gem slip jig?
It is a tune in 9/8 time that has a strong commercial recording history (recorded multiple times by professional artists) but is rarely bookmarked by users or played in modern session sets, making it a perfect candidate for revival.
Why are there so few slip jigs classified as hidden gems?
Slip jigs are a less common rhythm than reels or jigs in traditional sessions, and the active repertoire is heavily concentrated around a handful of classics like The Butterfly. This leaves very few tunes that meet the hidden gem criteria.
