Bagpipe Tachum
The tachum is closely related to the taorluath and uses a similar three-note construction. It is most commonly encountered in 6/8 marches and jigs.
Structure of the Tachum
Like the taorluath, the tachum uses the note sequence D — Low G — Low A, but the rhythmic placement and execution vary depending on the time signature and the specific passage. In 6/8 time, the tachum is often placed so that the Low A falls on a weak beat, giving the passage a lilting, forward-moving feel.
Tachum vs. Taorluath
The two embellishments use the same notes and the same basic finger movement. The distinction is largely in their musical context:
- The taorluath is characteristic of 2/4 and 4/4 marches and strathspeys, where it adds weight to a note.
- The tachum is characteristic of 6/8 marches and jigs, where it tends to fall in a lighter rhythmic position.
Practicing the Tachum
If your taorluath is already clean, the tachum should come relatively quickly. The physical movement is the same; what changes is where in the bar you place it and how it interacts with the surrounding notes. Work through a 6/8 march slowly, identifying each tachum before you try to play it at speed.
