1 3 5

Hi,

After you have memorize the fretboard on the bass guitar, it's time to create some simple bass lines.

If you have a song with chord progression like G Em C D, you should have no problem playing the root note (i.e G E C D )

You will sound right just playing the root note but now you also want to start playing a bit more. You can use 1 3 5 (notes inside a chord) to create something more interesting.

Let's write out the 135 in each chord:

G - G B D
Em - E G B
C - C E G
D - D F# A

Say I start with G and want to link to the next chord Em, I can play G B D E.
Next from Em I can play G B B C then E G G D

This is just the basic idea of creating bass line using 135. You can take it from here and explore which note sound better and try to get a nice line.

Cheers
