Here are the fingerings that I use to play a chord-melody arrangement of Johnny Burke and Erroll Garner's 1954 standard Misty. I play it in the key of C not the original key of Eb. The song is a medium ballad played in 4/4 time.
K. J. McElrath, Musicologist for JazzStandards.com explains it this way: "Called the ultimate love song, Garner wrote Misty in the 32-bar A1-A2-B-A2 form with no verse... The chord progression of section A is actually quite similar to that of Cherokee (I v7 I7 IV iv I vi ii7 V7) until measure 6 (while the ii7 V7 in measure six would work in the latter tune, its ii iii7(b5) turnaround would clash badly with the melodic pitches of the present tune). The first ending uses a lovely delaying, circle-of-fifths cadence starting on III7 (G7(b5) in the original key) before returning to the tonic for the second A.
Section B begins with a fairly orthodox harmonic progression v I7 iv, in which the I7 functions as a V7of the new subdominant key (in the original key, Eb modulating to Ab). But then the IV chord (Ab) is followed by a minor 7th chord a half step higher. Aural experience tells our ears to expect this Am7, which is followed by a D7, to be a ii7 V7 sequence to G major or G minor. Instead, Garner surprises us once again by a deceptive resolution to Cm, the vi of the original tonic of Eb. From there, its an easy modulation back to the tonic (but what a fascinating detour!)."
