Hello there, the tune starts like this
e---0---0---0---|
B---2---0---0---|
G---2---2---1---|
D---2---2---2---|
A---0---2---2---|
E-------0---0---|
It starts by doing this a few times then then it changes slightly
e---2---0-|
B---3---0-|
G---4---1-|
D---4---2-|
A---2---2-|
E---2---0-|
I can't be arsed weiting out a rythm but you should pick it up pretty easy
then:
[ Tab from: https://www.guitartabs.cc/tabs/j/jj72/oxygen_tab_ver_6.html ]
e---2---2---4---5-|
B---3---3---5---6-|
G---4---4---6---7-|
D---4---4---6---7-|
A---2---2---4---5-|
E---2---2---4---5-|
then start strumming the dm fast and then wuickly move up to a dm at
the 12th fret:
e---13(15-|
B---15----|
G---14----|
D---0-----|
A---------|
E---------|
Strum this for a bit and add the G with the little finger
(you'll pick it up from the song)
and then go back into the starting chords again
cheers
TOM
