"The favorite Scotch airs in score...as they are perform'd in the tragedy of Macbeth at the Theatre Royal in the Haymarket" represents a rare survival, a fully orchestrated score for a dramatic production, dating from the second half of the eighteenth century. Most of such music survives only in keyboard reduction.

Arnold provided two newly-composed items for the play: a march for Macbeth, and a minuet to be played in the banquet scene. Scottish tunes in general currency were orchestrated for interpolation into the play at points specified by Arnold:
Before the play: Berks of Endermay (The birks of Invermay), The yellow hair'd laddie;
At the end of act 2: The braes of Baladine (Ballenden)
At the end of Act 3: Lohaber (Lochaber)
At the end of Act 4: Earl Douglas's lamentation (The Earl of Douglas's lament).
Names in parentheses are the most common or standard spellings.

All of these items are available as individual notAmos editions.
