The Old Bush, a traditional Irish reel, carries a subtle sense of mystery as it moves between major and modal colors. That shifting character suits the tune’s title, which reflects a traditional respect for the otherworldly “fairy folk.”

C-Natural or C-Sharp? Although The Old Bush is generally regarded as a D Mixolydian tune, it makes selective use of C-sharp notes. Most of the tune uses C natural, giving it a distinctly modal sound. The C-sharp appears mainly in ascending phrases that approach D, functioning as a temporary leading tone rather than a permanent change of mode. As a result, the tune retains its Mixolydian character while occasionally borrowing a touch of D major for melodic lift and resolution.

If you’d like a quick refresher on Mixolydian mode, see the article “Dorian, Mixolydian, Oh My: Modes in a Nutshell” for a brief and friendly explanation.

The Lore — In the Irish landscape, a lone thorn bush standing in a field is rarely just a tree. The “old bush” (An tSeansceach) is traditionally associated with the “people of the mounds,” or fairy folk (Aos Sí), and such trees are often left untouched out of respect. These solitary bushes are most often hawthorn, or whitethorn, long associated with the unseen world. (Pronunciation: An tSeansceach ≈ “on tyan-SHYAKH”. Aos Sí ≈ “ees SHEE”. You can hear both spoken at Abair.ie.)
