A highland is an Irish musical form in duple meter, largely idiomatic of County Donegal.
Like its Scottish cousin, a fling is played in cut time and has a dotted rhythm.
Like the Scottish strathspey, quarter notes may sometimes be articulated as triplets or Scots snaps.
However, unlike the strathspey, these Scots snaps are usually less sharply articulated.
A typical fling has a 32-bar form divided into two parts, each consisting of eight bars which are repeated: AABB.
