| Find the root key in the left column and jot down the numbers of the chords in the piece. Chords are shown by the number system, based on the scale. Now move to the key to which you wish to transpose and convert the numbers back to chords. Add modifications to the chord (i.e. major, minor, 7th, 9th, etc.) to match your source chords. Note: I've deliberately elected to go with whichever scale was least confusing, thus, Bb instead of C# (Same notes but Bb is less confusing than C#). |
| Note: Composers aren't restricted to any particular structure, they can use any chord they like, anywhere they like. If the composer uses natural sequence chords (all notes remaining within the scale of the key) the 1, 4, and 5 chords will be major, while the 2, 3, and 6 chords will be minor. The 7 chord is based on a flat 7th rather than the actual 7th note of the scale. This chart isn't intended to cover every piece of music, but it should be effective for most songs. |
