Advanced studies explore using major, harmonic major, and harmonic minor pentatonics over complex progressions like Giant Steps.
Pentatonic scales are a key starting point for improvising, particularly on guitar, as they remove "risky" notes (the 4th and 7th), ensuring notes rarely clash with the underlying chord.
If you can tell me your and skill level (e.g., beginner guitar, intermediate piano), I can suggest the best type of pentatonic study method for you.
Research into using "non-standard" pentatonic scales (e.g., Hirajoshi) to add color. 3. Theory & Composition
While commonly used in blues/rock, studies show how to use them to suggest modes such as the major and minor pentatonic modes.
Studies show that pentatonic sequences can increase delta, theta, and alpha oscillations in the brain, contributing to a calm state.
