Here is a chord progression which utilizes a series of "altered" chords:

In the key of "D^b major":


"Fmin7 (b5) -- B^b7 (b9) -- E^bmin7 (b5)"

1) Fmin7(b5)

Bass = F
Right hand = A^b + B + E^b

2) B^b7 (b9)

Bass = B^b
Right hand = A^b + B + D

3) E^bmin7 (b5)

Bass = E^b
Right hand = A + D^b + E^b + G^b

Note: You should be able to find a place to "squeeze" this chord progression in. It is very pretty when used at the right time. Let your ear be the judge!
