Important Note
You can play the chords using any combination of these keys.
For Example : The chord of C Major can be played in the following ways

Piano Chord	1st Key	2nd Key	3rd Key
C maj 1st Position	3	7	10
C maj 2nd Position	7	10	15
C maj 3rd Position	10	15	19

As you can see for position 2, the C note ( key number 3 ) in position 1, is moved to the next octave up ( key number 10 ), and the same can be applied to all other keys.
