|The Transposition Chart is made up of the chromatic scale arranged
in rows and columns.
To transpose from one key to another:
Locate the row that starts with the letter name of the key the song is
To find the letter name of the chord in the new key, simply read across
from the original key to the new key.
When transposing chords of a song from one key to another the only thing
that changes is the letter name of the chord. For instance changing a
Cmaj7 to Gmaj7 only changes the letter name of the chord.The chord type
(in this case the maj7 part of the chord name) doesn't change.
Let's use the chord progression Cmaj7, Am7, Dm7-5, G9, Cmaj11 which is
in the key of C, and transpose it to the key of G. C is the forth row
down on the chart. G is three up from the bottom of the chart. The first
chord to change is the Cmaj7. The C in the forth row matches with G in
the third row up from the bottom, so the Cmaj7 becomes Gmaj7. The A in
the forth row matches with E in the the third row up from the bottom,
so the Am7 becomes an Em7. Likewise Dm7-5 becomes Am7-5, G9 becomes D9,
and Cmaj11 becomes Gmaj11.
Let's transpose the same chord progression from the key of C to the
key of E.
is the 7th row down. Notice that this cell in the chart has a sharp sign
and a flat sign ()
in it. That is because it represents D
On a piano this would be the black key above D or below E. The C in our
chord progression matches the E
in the seventh row, so Cmaj7 becomes Emaj7,
Am7 becomes Cm7, Dm7-5 becomes Fm7-5, G9 becomes B9,
and Cmaj11 becomes Emaj11.
