A Mandolin is normally rested in the lap and for a right-handed player, the fretboard and tuner point out to the left.
If you're picking up the bass guitar for the first time, a bass fretboard chart might be just what you need to keep the beat.
In a nutshell, a fretboard chart tells you which notes sit where on the fretboard of your bass.
Fretboard charts have one "line" for each string on the bass, and as you progress from left to right down that line, you'll see the note that is created when you pluck the string while pressing each string to a particular fret.
As a beginning player, you could be just a fretboard chart away from playing your first song.
