Toarluadhs and the like have changed considerably over the last 3 hundred years.
From; low G/d/low A /E/ A
to; low G/ D/ low G / low A/E/ A
to ; Low G/D/G/E/A
The original taorluath movement was much more rhythmically complex and open than is performed today. (altpibroch.com). 
Today the older version is known as the “redundant A” taorluath, and few people play it. And yet,  the rhythmical expression is very pretty, the movement sounds quite dexterous, and the melody is retained.

It is worth noting that today’s taorluath movement was introduced as late as 1907 with John McLennan’s collection; thereafter the Piobaireachd Society adopted it.  

This is a grip with a E gracenote added onto it before ending on the melodic note. Therefore, all that applies to Grips applies here as well. The E gracenote is what leads to the melody note. The E gracenote is played on the beat.

The steps to play the Taorluath:

  1. Play Low G
  2. Play a D Gracenote on Low G
  3. Play E Gracenote to any other note lower than E.

Things that can go wrong:

  • Crossing noise to Low G
  • Poor D Gracenote length
  • Poor D Gracenote Timing
  • Poor E Gracenote length
  • Poor E Gracenote Timing
  • Crossing Noise to next note
  • Steps played unevenly
  • Timing such that embellishment isn’t on the beat (E Gracenote on beat).
There is a variation on the Taorluath where if you are coming off of the D, you use a B gracenote instead of a D gracenote.

The Toarluath is introduced in SCQF Level 3.

In Canntaireachd, the Taorluath is known as a darid.



The symbol for the Taorluath beat is darid, e.g.,

Taorluath to low G is darem, e.g.,

  • hiodarem.
