Under the Full Moon by Catherine Wilson is eerie and mysterious with an unsettled feel.  
 
The left hand uses quasi Alberti bass motifs that give the piece a timeless quality while the right hand melody contains an abundance of tritones, giving it an edge of uncertainty to what may happen next, though it ends with a Tierce de Picardie suggesting more settled times ahead!
