My Creative Jazz Exercises, Volumes 1, 2, and 3 2nd Edition (updated and improved from 1st Edition versions sold by some companies: Charles Colin, Sam Ash, Amazon, etc). These books comprise a complete method to develop technical skills in reading and contemporary improvisation. Accompaniment files have been created using iReal Pro - https://irealpro.com and can be customized in many ways. They serve as a tonal metronome so you can hear the harmonic concepts being presented. The exercises can be used as a starting point for improvisation using various approaches for guidance.
Volume 1 focuses on reading and patterns using chromatic, fourth and pentatonic shapes. It also delves into varieties of blues scales. Exercises are technically challenging but will result in great flexibility and harmonic strength. Volume 2 is based on substitute scales and chords; using harmonic groupings starting on different roots. Volume 3 is based on "back of the mind" approaches that serve as a launching point for improvisation. Examples for each approach are provided, including reading exercises that combine approaches..

Adjust the tempo, groove, etc to personal taste. Some of my students initially slow down the tempo then increase speed. You can mute the keyboard or guitar to create more space, especially with Fourth, Chromatic and Sub-Chord exercises.
