“I've been using and teaching from Darius' Umbilical Chords chart since its release in 1995 and swear by it.

Browse over it at its most basic level and it serves as a great reference for scale, mode and chord shapes. Dig a little deeper however and it becomes a pivotal resource for learning and teaching the mode-to-chord relationship with the tools to turn theory into music.

I think every serious guitarist and teacher needs one on their wall”.
