Night and Day is a tune that can feel deceptively simple on the surface, but the real challenge lies in how its harmony moves and how great players shape long lines across the form.

In this lesson, you’ll focus on a single section of Night and Day and study how Kenny Garrett approaches it in his solo. Rather than trying to digest an entire transcription at once, this approach allows you to isolate specific musical ideas and absorb them in a focused, practical way.

By examining how Kenny develops phrases, navigates harmony, and creates forward motion within one section, you’ll begin to understand how master improvisers extract deep musical value from small portions of a tune. These concepts translate directly into your own playing on Night and Day and beyond.

Minor ii–V progressions are a defining feature of Night and Day, and they’re often where improvisers feel the least secure. One reason for this is that the harmony can be often be viewed from more than one valid perspective.

I often think of the first chord as bVI major (B major in the key of Eb, Ab major in the key of C), while many charts label that same sound as a ii half-diminished chord (F half-diminished or D half-diminished). In practice, these are simply two different ways of understanding very similar harmonic information — and knowing both perspectives gives you more flexibility as an improviser.

Without a clear conceptual approach, the combination of half-diminished harmony, altered dominant sounds, and shifting color tones can quickly lead to uncertainty.

In this lesson, you’ll learn how Bill Evans conceptualizes the minor ii–V not as a collection of scales, but as a flexible harmonic environment built from chord tones, voicings, and implied alterations. You’ll see how dominant chords in minor can be treated simply while still offering endless expressive possibilities.

Mastering these concepts allows you to navigate the minor ii–V passages — or the bVI major sound, if you prefer to think of it that way — in Night and Day with confidence, clarity, and musical intent instead of hesitation.

Turnaround like progressions play a major role in how Night and Day flows from one section to the next. These brief harmonic moments are where tension builds, anticipation forms, and the music naturally wants to move forward.

In this lesson, you’ll explore seven essential turnaround concepts used by great improvisers to create momentum and melodic interest. Rather than treating turnarounds as fixed chord progressions, you’ll learn how to imply harmony, suggest substitutions, and shape lines that lead convincingly back into the form.

Applying these turnaround ideas to Night and Day gives you greater control over the tune’s harmonic motion, helping your solos feel intentional, fluid, and connected instead of boxed into the written changes.

Learning a tune like Night and Day isn’t just about memorizing chords — it’s about understanding where it fits within the broader landscape of jazz standards.

In this lesson, you’ll explore how common song forms like AABA and ABAC shape much of the jazz repertoire, and how harmonic construction connects many standards together. Night and Day shares structural DNA with countless other tunes, making it an ideal vehicle for building long-term repertoire knowledge.

By understanding the form and harmonic relationships behind Night and Day, you make it easier to learn new standards, recognize familiar patterns, and move more efficiently through the Great American Songbook as a whole.
