How to keep your left hand in place for a C chord:

First, place your left hand in C position, with your fingers ready to play a C chord.

Now close your eyes and imagine that your thumb is glued to the piano and no matter what, you can't move it.

Make sure your other fingers are in position to play C chord. With your eyes closed, play four C chords in a row.

If any of your other fingers accidentally move out of place, do not look to find their place because if your thumb is glued to the right key, all you have to do is feel the keys with your fingers to find their place again.

If you move your thumb, you will have to look to find your place again, so do not move your thumb. The key that your thumb is glued to is G.
