Thomas Carter's 'Awa, whigs, awa!' is a piano arrangement of a traditional Scottish air. It features a simple, folk-like melody and a gentle, perhaps slightly melancholic character.
Work on maintaining a steady tempo while allowing the melody to sing out clearly over a simple accompaniment.
Awa, whigs, awa! is rated Henle level 3 of 9 — late beginner repertoire, roughly ABRSM grades 4–5. In the RCM system it corresponds to about level 6.
You should be comfortable at Henle level 3 — meaning you can already play level 2–3 pieces cleanly. Learning it one level early is possible as a stretch piece, but more than that usually leads to months of frustration.
A typical performance of Awa, whigs, awa! lasts about 3 minutes.
