Cooley’s Reel is one of the absolute titans of the traditional Irish music repertoire. If you walk into a traditional session anywhere in the world—from Galway to Boston—and someone strikes up the opening notes of Cooley’s, every musician in the room instantly knows exactly where they are.
It is a tune with a powerful driving energy, balancing a distinct rhythmic pulse with a beautifully melodic flow.
Here is a breakdown of what makes this reel so enduringly popular:
The Musical Signature
-
The Mode: The tune is played in E Dorian, giving it a characteristic “shadowy” or atmospheric quality. It isn’t strictly minor or major, but sits beautifully in that ancient, modal sweet spot that defines so much of Celtic music.
-
The Structure: Structurally, it is a standard 32-bar reel divided into two parts (A and B), each played twice.
-
The “Cooley” Roll: The A-part kicks off with a powerful, low-register drive focused heavily on the low E string, making it an excellent showcase for strong bow-work on the fiddle or precise flatpicking on the mandolin. The B-part takes flight, climbing up into the higher register with a brighter, lifting melody before rolling back down to that grounding E bass note.
The History and Name
While the tune is older than its common name, it owes its global fame to the legendary button accordion player Joe Cooley (1924–1973) from County Galway. Cooley was a force of nature in the mid-20th century traditional music revival, known for his driving, rhythmic, and deeply soulful style.
He didn’t compose the tune—it was originally known by titles like Luttrell’s Pass or Put the Cake in the Dresser—but his definitive performance of it with the famed Tulla Céilí Band stamped his name on it forever.
In the Session
Cooley’s is universally loved because it is incredibly accessible for developing players, yet it leaves infinite room for masters to add subtle ornamentations, triplets, and variations. It is almost always paired in a medley, most famously transitioning immediately into The Wise Maid or The Maid Behind the Bar to keep the energy in the room climbing.
In traditional Irish sessions, Cooley’s Reel is famously treated as a building block for higher-energy sets. Because it sits solidly in the lower register during the A-part and builds momentum, it pairs perfectly with tunes that offer a contrasting lift or a shift in key.
Common Session Medley Pairings
The transition out of Cooley’s is an art form. The goal is usually to move from its heavy, driving E Dorian flavor into something bright, major, or rhythmically lifting.
-
The Classic Progression: Cooley’s → The Wise Maid
This is arguably the most ubiquitous pairing in the traditional world. The Wise Maid (composed by John Dougherty) is in the key of D Major. Moving from the atmospheric E Dorian of Cooley’s straight into the bright, ringing open D strings of The Wise Maid gives the session an instant, joyful “lift.”
-
The High-Energy Follow-up: Cooley’s → The Maid Behind the Bar
Another definitive D Major reel. The rhythmic syncopation of The Maid Behind the Bar picks up the steady, rolling momentum left behind by Cooley’s and drives it home beautifully.
-
The “Big Set” Expansion: The Banshee → Cooley’s → The Maid Behind the Bar
Sometimes Cooley’s isn’t the opener; it’s the middle engine. A massive session staple involves starting in G Major with The Banshee, dropping down into the moody E Dorian driver of Cooley’s, and then bursting out into D Major for the finale.
Sheet Music Notes: The A-Part
The A-part of Cooley’s Reel is highly recognizable due to its foundational “E-B-B-A” rhythm. It focuses heavily on standard ornamentation options like cuts and short rolls on the B and E notes.
In standard traditional notation (played with a two-sharp F# and C# key signature for E Dorian), here are the exact notes for the 8-bar A-part, split into its logical phrases.
Phrase-by-Phrase Breakdown
-
Measures 1 & 2 (The Hook):
E B B A | B2 E B | B2 A B | d B A G
The classic opening phrase. It hits that low E, jumps up to a sustained B, and cascades down through a crisp d B A G run.
-
Measures 3 & 4 (The D-Major Contrast):
F D A D | B D A D | F D A D | B A G F
The melody answers by dropping onto the open D string, rocking back and forth against the melody notes before resetting.
-
Measures 5 & 6 (The Repeat & Climb):
E B B A | B2 E B | B2 A B | d e f g
The hook repeats, but instead of cascading down, it runs right up the scale (d e f g) to bridge seamlessly into the resolution.
-
Measures 7 & 8 (The Turnaround):
a f e ^c | d B A F | D E F D | E3 D
A rapid descent from high A, utilizing a sharp C (^c), falling right back down to a solid, grounding low E root note.
If you are working this out on an instrument like the fiddle or mandolin, keeping that first finger glued to the E-string’s B note during the opening bars allows you to drive the rhythm with clean, powerful picking or bowing patterns.
