As in the G 5 example you have to stop a string from sounding - this time it's
the 4th string that you have to touch with the finger that is getting the C
note on the fifth string to damp it off.
See the tab for some other C 5 shapes
The notes in brackets could be added to the chords.
See below the tab for a full 6 string version using left hand thumb to get the root note.
