You already used the free explorer. The Pro pack is its printed companion. Every shape across all 24 keys, drawn for paper and made to live on the music stand, one key a day for a month.
The C, A, G, E and D shapes mapped in all twelve keys, major and minor. The same map you learned in the explorer, now for every key you'll ever play in.
Every shape comes with its arpeggio and pentatonic overlays, so you see the chord, the notes that decorate it, and the scale that surrounds it on one board.
One key a day, in a structured order, with the drills that make each shape stick. Thirty days from page one to the whole neck under your fingers.
Thirty pages built for paper. Print them, mark them up, keep them on the stand. No app and no login, and it stays yours for as long as you play.
If you've played a while, you already know the five shapes. The Pro pack connects them across the neck, so the CAGED system stops being five separate boxes and becomes one map you can read in any key.
