Transposing Chords

Transposition is when you move something from one key to another. This concept is simple to use and grasp. The easiest way to transpose is to have a listing of the notes of all the major scales in front of you (as shown in the chart below). Let's say that you have a chord progression of C - F - G, and you want to transpose it to the key of A from the key of C. You would go to the C major scale in the chart (below) and see that C is the I degree, F is the IV degree, and G is the V degree. Now you must go to the A major scale and see that the I degree is A, the IV degree is D, and the V degree E. So what you would do is play an A - D - E progression instead of a C - F - G progression.
Note: If the chord is a Cmaj7 then you would change it to an Amaj7. The same applies for any other type of chord.
