Brown Eyed Girl
How nice of Van and his band to start the song with just the bass line. Thanks, man! If you're having trouble hearing the bass in these other examples, start here.
On the flip side, the bass player doesn't dilly-dally on his root notes. You'll need a quick reflexes to pause the song at the right time, and keen ears to hear the note for a split-second before it changes.
Island in the Sun
This is a great example of a song that would be hard to decode without the two superpowers you now possess. Why? The main guitar riff uses chord voicings played higher up the neck than standard open chords, and they lack bass notes. But those high voicings actually make it EASIER to hear the bass notes, which is what you're supposed to be listening to anyway, right?
The bass line kicks in halfway through the intro.
