Justin,
Where can I purchase the Chord Construction Guide you mentioned in this video?
Thanks,
Joy
@Player27 Justin used to have some materials and resources as available to purchase as pdf downloads. Chord Construction was one of these. The content and teaching was updated and moved into the new Practical Music Theory Course. by taking a subscription to that course he includes all the previous pdf resources.
I hope that helps.
Cheers
