The first song on the Play Bass in 50 Songs – Rock list is Yellow by Coldplay. Paul Wolfe writes:
A nice simple line to get started with.
And so it is. Consisting of only 2 sections and using just 5 notes in total on a straightforward quaver/eighth-note rhythm, this is close to as easy as it gets.
The official video for Yellow is here.
And that should be everything you need to master this song’s bass part.
Have fun y’all.
