What i do with most Gaslight acoustic songs is put the capo on third fret in standard tuning then transpose the original chords so original verse progression is C , Am , G , that becomes G , Em , D .
So verse is G ,Em, D. On the' again' of 'Dying to breathe again' play C , Em , D once in the same rhythm then return to the G , Em, D progression. All the verses follow this pattern.
The chorus is the same , go to the C, Em , D on the 'stone' of 'Heart of stone'.
The bridge is C, Em , D repeated .
