This is a song designed to be improvised with on any keyboard instrument. Of course the keyboard must be in tune with 440 pitch. As long as the improvisor stays on the white keys there will be harmonic peace. Some have said that a true Dorian mode must resolve to the d minor chord. Dorian has a B natural if D is your tonic note. This song resolves to the e minor chord and some say it is a phrygian song instead. What do you think? There are lots of toys used by the percussionist, Leon Schwartz and the pianist, Bobby Pancoast. This song is a good preparation for jazz improvisation whatever your instrument.
