This is wonderful!
I can now start to see how the shapes kind of jigsaw together, rather than thinking of five-fret-wide boxes that run across the strings but never up and down them…
I’ve tuned up my 7 string in 4ths to make learning the fit between them a bit easier, as (to may way of thinking at least), accounting for the G/B switch on a 6 will be a cinch later rather than building in this oddity (it can be argued) from the off.
Thank-you so much for posting this.
