A hands‑on workout focused on tritone sub voicings, extensions, and upper‑structure practice to improve jazz chord transitions.
Practice an all‑in‑one progression that uses tritone substitutions, open and closed voicings, and 7#11/13 upper structures to create richer dominant sounds. Learn how to voice sub5 dominants (half‑step approach) as 7#11 chords, extend them to 13ths, and layer upper‑structure triads (e.g., 27 and E7 over D7). The lesson includes guided examples in C and suggests practicing in one key, several keys, or around the circle of fifths; a PDF with the exercise is available for download.
