Hope it helps you! I am finding that the more I practice them, the less I depend on them. There are 5 unique strings and all boxes consist of 2 4-fretters followed (or preceded) by 3 3-fretters. Learn where the 4-fretters go for each box. There's a pseudo pattern from box 4 back around to box 3. Box 4: 5&6 Box 5: 3&4 Box 1:1&2 and then, Box 2: 4&5 Box 3: 2&3 (1st 4-fretter is shifted) String 1 = String 6 and vice versa When you cross from string 3 to 2 you need to add a fret and vice versa Minor Box Roots: 2nd 4-fretter 1st finger, 2nd 3-fretter 2nd finger Major Box Roots: 2nd 4-fretter 2nd finger, 3rd 3-fretter 1st finger Blues Notes (Major and Minor): Between the first 3-fretter and after the last 3-fretter.
