This chart is intended as an aid in transposing. For example, if you are transposing from A to C, use the A row (row 1) to identify the chord, and then go down to the C row (row 4) to find the transposed chord.
Example: | A | C#7 | F#m | Em | D7 | Ebdim7 | A | C#7 | F#m | B7 | E7 | A |
C | E7 | Am | Gm | F7 | F#dim7 | C | E7 | Am | D7 | G7 | C |
