Reel, D Dorian
By Bobby Casey (1926-2000)
TrailJams Tune of the Week: February 8, 2026

With its steady center on the pitch of D, this Irish reel has a hypnotic and meditative groove. The tune was composed by Bobby Casey (1926 – 2000) of County Clare, Ireland.
D Dorian
Being entirely in D Dorian, the tune uses only the notes of the C scale, and fits nicely on a C tin whistle. If you are a bit hazy on the Dorian mode, see the article “Dorian, Mixolydian, Oh My: Modes in a Nutshell” for a brief and friendly explanation.
The Kelp and its Porthole
The Kelp, as Bobby Casey tells it, was the name of a ship. He and his cousin encountered the Kelp aground on the beach at Spanish Point, on the coast of County Clare, Ireland. His cousin kept one of the ship’s portholes as a souvenir, and it was that keepsake that inspired Bobby to name this tune “The Porthole of the Kelp.”
There are records of a 127-foot steel-hulled cargo ship named the Kelp that wrecked at Spanish Point in 1916. The Kelp may have been a sailing schooner or (as the illustration above suggests) a steam-powered freighter. The shipwreck occurred ten years before Bobby Casey’s birth, and is probably the ship he refers to.
