The broadest mDecks collection: a large library of books, courses, workouts, repertoire, harmony, improvisation, and voicings.
The Colossus Bundle is designed for breadth rather than a single learning path. It brings together a large portion of the mDecks catalog across jazz harmony, improvisation, piano technique, voicings, scales, repertoire, composition, and specialized workouts, making it useful as a long-term reference and teaching library.
