A quick tip to find the chords of any simple tune: place your thumb on the key note, C for example, on a piano and lay your fingers on the others so that they cover D, E, F and G. Your main three chords will be Thumb (Key note), fifth finger and fourth finger, In this case, C, G and F. The minor will always be three semitones from the Key note, e.g., going down from the Key note, B, Bflat and A which is your minor. This applies no matter where you place your thumb on the keyboard.
