In this how-to video, you will learn how to tune your bass. This is important, as weather can affect your tuning. Every time you pick up your bass, you should tune it. First, start with the low E string. You will need to listen to a reference E note to tune this string. A tuner or piano can be used. Go to the fifth fret on the E string and tune the open A string to this note. Tighten or loosen up the string accordingly. Now, go to the fifth fret of the A string to tune the D string. Next, go to the fifth fret of the D string. Tune the last string, the G string to this note. Now your bass is tuned. An electronic tuner is also useful for doing this.
