Many thanks for your comment. If I remember well, the original song is half step down. So to obtain original tune you have to drop from E to Eb. If u use a capo you'll raise instead to drop. IF I REMEMBER WELL 😉
Your statement would be correct if there weren't the tabs which, with a mobile nut, would not be very intuitive. in this way the tabs are usable both by those with standard tuning and dropped by half a tone. considering that the vast majority of guitarists have a standard tuning I thought of playing it like this. for those who want to be the same as the original, just tune half a tone below without any alteration in the tabs themselves
