In a 1978 interview with Marian McPartland (in fact Bill was one of Marian’s first guests on her radio program, Piano Jazz), Marian queried, “How do you think your playing has changed since you first started? Is it deliberate or is it just happening to change?” Bill, being a very cerebral person who spent countless hours working on his aesthetic, replied, “Well it’s deliberate, ahh but I stay along the same lines…I try to get a little deeper into what I’m doing. As far as that kind of playing goes, [jazz playing rather than an earlier example where he played Waltz for Debbie without any improvisation or sense of swing], I think my left hand is a little more competent and uhh…of course I worked a lot on inner things happening like inner voices I’ve worked on.”

I would like to explore the “inner things” of Bill’s version of Danny Boy. You can find my part extraction below. You should take note that most of the motion within the inner voices is by step and in the case of disjunct motion, Bill tends to follow the rules of good voice-leading.
Beginning with the anacrusis:
In the alto voice, Bill uses the 9th of the F9 chord to ascend in stepwise motion to the third of the chord. Meanwhile, in the tenor voice, he doubles the melody note with a Bb3 and subsequently descends to the A3 (this motion acts something like that of a Sus4). Keep in mind that although the motion seems to imply a suspension, I contend that Bill was using the Bb3 as a color tone to capitalize on a quartal sound. Also of note is that the fact that, although it is only within the context of two beats, Bill uses contrary motion between the alto and tenor voices — something that is paramount within counterpoint of the classical canon.
Meaure 1:
In the alto voice, Bill uses the ascending motion from the anacrusis to arrive at the tonic of the Bb (I) chord. Meanwhile, in the tenor voice, he uses the A3 from the previous measure as a lower neighbor tone to return to the Bb3 in measure 1. I assure you, these movements are not coincidental — Bill was very deliberate in choosing his voicings. The measure continues with a series of chordal skips in the alto voice: Bill moves from the Bb4 on beat one to F4 and ultimately D4 on the final beat. He chooses to keep the Bb3 within the tenor voice for the entire measure.
Measure 2:
This measure adds some more colorful voice-leading and consequently, harmonic movement. Notice how Bill, in the alto voice, leaps from the previous D4 of the first measure, to the G4 on the following downbeat. Leaps of this kind are generally considered to be improper in earlier modal counterpoint and are often looked as unfavorable in tonal counterpoint (unless the leap is followed by a stepwise motion in the opposite direction). I believe that Bill, temporarily forgoing the rules of voice-leading, uses this leap to accent the 13th of the Bb chord. Additionally, if you think in terms of the greater picture, Bill does, in fact, resolve the leap by descending (by step) to the F4 in measure 3. I would also like to point out how Bill forecasts, in somewhat of an imitative move, the leap in the melodic line: D5 to G5 to F5. Brilliant.
In terms of the tenor voice, as is the proper thing to do, Bill employs oblique motion: while the other voices are moving in conjunct or disjunct motion, the tenor voice remains stationary.
Measure 3
After a series of rests in the alto voice, Bill resolves (as previously mentioned) the G4 to the F4 in measure. However, in typical Evans fashion, he chooses to create a subtle dissonance between the G4 and F4. As an aside, author Ashley Kahn once mentioned, “he hits these chords that have such a dissonant effect — a little like Thelonious Monk, but quieter and smoother. He just sounds so startling different from what’s expected in jazz, yet so hip and modern at the same time.” Because Evans had such dynamic control of his instrument, he was able to produce the dissonance within the inner voices with such nuance.
As the alto voice remains somewhat stationary, Bill chooses to add movement to the tenor voice. He leaps across the barline from the previous D4 to the Bb3 on the downbeat of this measure. As is traditionally expected, he follows the leap with stepwise movement in the opposite direction: he then ascends from the 5th of the chord on the first beat to the passing tone C4 — ultimately reaching the M7 of the Eb sonority.
Measure 4
This measure ends the first phrase of the tune and Bill, understanding this, evokes such a sense of lament and beauty.
The alto voice, due to the prominent movement of the outer voices, is grounded through oblique motion.
The tenor voice, after the stepwise ascent in measure 3, moves downward by step from D4 to C4. Bill also, in typical fashion, adds a tritone beneath the C4 with a Gb3. This quiet dissonance adds so much flavor to the inner voices, but primarily acts as the 7th of the presiding Ab7 chord.
