This is a new tool for users of the ableton push in learning harmony. It contains a list of ready to go chord progressions and their positions on the push. With over 50+ push chord progressions taken from popular music this collection will give you over 100 variations in major and minor modes alone. (Includes an Ableton project file with midi to help you practise the chords in major and minor keys).
Additionally, it can also be paired with the different chord shapes and types in the Free push chord reference, which shows different chord shapes rather than progressions. The chord & progression reference can be used together to create chord progressions with extended 7th, 9th, 11th, 13th chords and more based on these popular harmony progressions.
If you want to dig deeper, there is a list of number permutations of patterns that can be applied to progressions – with over 5000 variations on 4-7 chord patterns.
