The Invisible Man is personally my favorite Queen song of all time. Even the video is awesome! This is basically the main bass riff of the song; G|----------------------------|----------------------------| D|------------------------1/3-|----------------------------| A|-3-3-3--3-3-3-3-3-3-3-3-----|-3-3-3--3-3-3-3-3-3-3-3-----| E|----------------------------|------------------------6/3-| But during the bridge (the 'ha, ha, ha, hello' bit) G G|------------------------------| D|------------------------------| A|------------------------------| E|-3-3-3--3-3-3--3-3-3--3-3-3---| I think that's how it goes. Mind you, it's quite a funky bass riff throughout the song. D E G|------------------------------|------------------------------| D|------------------------------|-2-2-2--2-2-2--2-2-2--2-2-2---| A|-5-5-5--5-5-5--5-5-5--5-5-5---|------------------------------| E|------------------------------|------------------------------|
