These variations are based on the famous B Minor study by Fernando Sor (Op. 35, No.22; Segovia No. 5). The haunting melody has been begging me for years to be in tremolo ("Sor-ega") and that was the impetus to do these variations (and to move to E minor). The second variation, in E major ("Sor-cassi"), reveals the sunny side of this melody. I imagine it is a 'lost' study by Carcassi (Op. 60, No. 26!). The last variation, "Sor-os" considers what may have happened if Sor met Villa-Lobos.
