Jazz Basics - Lesson 7 - ii-V-I in C and B♭ major, flat 13 dominant chord, and more (English)

Jazz Theory Concepts:

Lesson 7 of the Jazz Basics course covers ii-V-I in B♭ major and expands on ii-V-I in C major, which we covered in Lesson 1. Flat 13 dominant chords are introduced, as well as inversion of the third and seventh notes for ii-V-I in C major and how this voicing can be expanded on to encompass a three-note voicing.

Using C Dorian (the second mode of B♭ major), the Dorian mode and its relationship to the ii of ii-V-I chord progressions are also covered, with an in-depth explanation of diatonic chord extensions from C minor 7.

Homework:

Improvise continuously from ii-V-I (or ii-V-I-VI) in C major to ii-V-I in B♭ major, with an optional addition of the flat 13 dominant chord. If improvisation is too difficult, use a metronome at a slow tempo and play the right chords and voicings on the right beat.

The chord progression should be as follows:

D-7, G7, CΔ7, (A7) → C-7, F7, B♭Δ7 with proper voicing and chord extensions.

Upgrades:

Like Lesson 6, Lesson 7 of Jazz Basics uses a perfectly-in-sync piano roll (one of those keyboards that light up whenever you play a key). Moreover, in Lesson 6, a piano roll is provided for the brief improvisation I played in the intro to this lesson, allowing intermediate or upper-intermediate players to analyze new voicings that are not covered in the Jazz Basics course.

A dynamic sheet music is also occasionally used to sync up with what's played as I explain jazz harmony concepts.

Most importantly, work hard, practice smart, and have fun!
