The basic chord of C, F, Am & G will make a magic music world in using inversion and passing note by both hands even we do not have a chance to learn how to play a piano. Just playing around in a piano will be a good practice of composing a wonderful music and enjoying ourselves.
Basically, playing a piano needs two hands, right hand and left one. Why do we use tow hands? Each of both will have a different function. Right hand will take care of a melody and will be a lead to the left hand in terms of movement of musice. On the other hand, the left hand will take care of rhythm and keep a core note to support the melody led by the right hands.
In the stage of practicing, both hands should repeat the touching the three noted of four chord. Left hand will be able to just touch a root position of each chord, and further, touch both a root position and octave position to a root position while the right hand will keep touch three notes of each chord.
The next step will be to change a root position. For example, chord c, we should touch c, e & g where the root position is c. If we change the root posiiotn from a to e, then we may toruch e, g & c or g, e & c. We may feel some changes, which make you less boring.
