From James Oswald - Caledonian Pocket Companion, vol. 1 (1760). It’s a slow air! Oswald used this as one of the 5 tunes he set for his "Sonata on Scots Tunes" (other tunes set : "O Mother what shall I do?", "Ettrick Banks", "She rose and let me in", "Polwart on the Green"), a lovely piece of music.
Alternatively, tune is called "Cromlet’s Lilt.
cf The ‘Scots Musical Museum’ - Volume II, song 199, page 207 - ‘Cromlet’s Lilt’ (quote follows)
‘Since all thy vows, false maid,
Are blown to air,
And my poor heart betray’d
To sad despair,
Into some wilderness,
My grief I will express,
And thy hard heartedness,
O cruel fair.’
This song is also known by the name of ‘Lament of Sir James Chisholm of Cromleck (Cromlet)’. Alive around 1600, this song relates his tragic love affair. The music and the words both have a seventeenth century courtly air in the rhythm of a galliard. As a result it is thought to have been performed as a court solo. It was first printed in Ramsay’s ‘Tea-Table Miscellany’ (1724-7) and continued to be sporadically reprinted until its appearance in the ‘Museum’.
