Stein's touch emphasizes the balladic quality of the opening before shifting into a grooving, swing-inflected middle section that feels both relaxed and propulsive.

Jazz pianists and serious students developing their interpretive vocabulary through studying recorded standards and classic arrangements. This resource works equally well for pianists preparing concert repertoire or those exploring how professional musicians approach the jazz canon.

• Pay attention to the harmonic substitutions in the voicings; they're characteristic of mid-century jazz piano and require listening closely to track your position in the form.

• Let the rubato breathe naturally in the initial statement of the melody, then lock into a steadier tempo for the swing sections.
