Box 5 anchors on the scale's fifth degree — D at fret 10 in the E minor pentatonic worked example — and it is the window that proves the system loops: climb out of its ceiling and you land in box 1's fingering, twelve frets above the open position, same shapes, octave higher.
The window, computed (E minor pentatonic)
| String | Frets | Notes |
|---|---|---|
| 6th string (E) | 10 / 12 | D / E |
| 5th string (A) | 10 / 12 | G / A |
| 4th string (D) | 9 / 12 | B / D |
| 3rd string (G) | 9 / 12 | E / G |
| 2nd string (B) | 10 / 12 | A / B |
| 1st string (E) | 10 / 12 | D / E |
Using it
That wrap is not poetry, it is arithmetic — twelve semitones up, every pitch class repeats, and the derivation that computed these tables produces box 1's pattern again at fret 12 (the table's note column shows the same letter names returning). Box 5 is also the door to dramatic endings: its top notes are the highest scale tones before the loop, and a run from box 1's floor to box 5's ceiling crosses the entire tiled map — the full journey of most climactic solos. Fingerings for every key: the scale reference.
