I love this lesson. It gives me goosebumps. cry

Thanks for posting that. A seminal example of the power of key change.

There's a difference, though, between an actual key change and whether that key change should be written into the key signature. I don't have strong feelings about that ... for me it's a tradeoff between recognising the key change from the accidentals or seeing the new signature and having to change my understanding of the accidentals.

I've been thinking throughout this thread of a particular example and the mention in the video of John Coltrane prompts me to mention it, and that's his "Giant Steps", which changes key something like every bar, to the extent that a written "key" becomes probably irrelevant. In practice one learns the chord progression and just "deals with it". The version I use is written in C Major and every chord/note/key is defined by the music as it's written.
