Discovering Jazz Guitar A practical introduction to jazz guitar — without getting lost in theory (or in your own fingers). Understand jazz chords and progressions with step-by-step lessons inspired by jazz standards, from Classic Jazz to Brazilian and Gypsy Jazz. This course is designed for beginners in jazz: you’ll learn real concepts and how to use them. It’s not a “first guitar” course though — you should already be comfortable with basic chords and basic rhythm (changing chords in time). What’s inside: 8 lessons with a gradual increase in difficulty. For each lesson: theory, tips, tabs, and video. Learn chord embellishments, diatonic substitution, and tritone substitution. Understand how to create your own jazz chord progressions. Lesson 1 — Jazz Chords Jazz chords built from the major scale. II–V–I chord changes in G and C. Introduction to walking bass. Lesson 2 — II–V–I Progression Using the major scale in progressions. Chord embellishment. The diminished chord. Lesson 3 — Changing Key Find II–V–I in multiple keys. Chord roots on the E and A strings. Lesson 4 — More Chord Movement Diatonic substitution. Secondary dominants. Cycle of fifths. Triads and tetrads. Lesson 5 — Tritone Substitution Tritone substitution in context. 11th and 13th chords. Practical fingerings. Lesson 6 — Blues for Clara From a traditional 12-bar blues to a richer form. 9th and 13th chords. Lesson 7 — Gypsy Swing Gypsy Jazz rhythm fundamentals. Major and minor 6th chords.

Verdict
The clearest difference is update cadence: Jazz at every 2 weeks against E's every 3 months. Jazz also leads on iOS requirement (15.1 vs 17.6). On price, ads, in-app purchases and device support there is nothing between them.
