One of the important Scottish collections, by James Aird in 1778.
It is often attributed to Goulding, the publisher, with no mention of Aird.
The full title is "A Selection of Scotch, English, Irish and Foreign Airs",
and if you see this, it probably refers to this collection.
Most of the tunes are arranged to fit simple flutes and fifes
and/or bagpipes, and it has been a major source for "vintage"
fife-and-drum and other military-style bands.
