When it comes to the vanilla C major chord Cat favors almost exclusively the following two shapes: either the standard C major shape with an added G in the treble (Figure 1) or the bassier C/G (Figure 2).

Cat is, however, not consistent in his application. He interchanges these chords at will. Take ‘Changes IV‘ as example. At ‘The Old Grey Whistle Test‘ he favors the first variant, whereas at his famous BBC Concert he opts for the more percussive C/G version for the very same song.

Similar deviations can be observed for songs like ‘Katmandu‘, ‘Father and Son‘ and many more. Even in the same song Cat may switch it up from one part to the next.
