Double Trouble is a book of unique duets by Stacy Fahrion. This book gives pianists opportunities to experiment with blues improvisation and extended techniques. It includes showy pieces in odd meters, several wild boogies, a melancholy lyrical waltz, and, of course, a tarantella that has Itsy Bitsy Spider surreptitiously woven into it. Most of the pieces are based in minor keys, modal, or use the double harmonic major scale.
