We are still working with the chords A min., D min. and E. In the Numbers system this is called a "1-4-5 in the key of A". If you will look at the numbers chart to the line that reads "Scale / key -- A" and locate the note letters A-D-E you can see that the letter "A" is under the number "1". The letter "D" is under the number "4" and the letter "E" is under the number "5".

We know the first chord name tells what key the song is in and we are going to transpose to C, so Cm is the key we are going to transpose to and also the first chord.

To locate the second chord D look at the numbers chart to the line marked "Scale / key -- A" and locate the note D.

Notice it is under the column number 4.

In that same column, 4, tracing down to the line marked "Scale / key -- C", you will run into the note letter F.

Use this same procedure again with the last chord E. To locate the third chord E look at the line marked "Scale / key -- A" and locate the note E.

Notice it is under the column number 5.

In that same column, 5, tracing down to the line marked "Scale / key -- C", you will run into the note letter G.

The E chord, (key of A), will transpose to a G in the key of C.

The transposed arrangement will be key of Cm, first chord Cm, second chord Fm, last chord G.

Take a little time to write down a few different chord patterns and then transpose to different keys.

You will be surprised at how simple this can be and it's very useful to any musician!
