Watch the Basic Box Shape online guitar lesson by Andrew Ford from Blues Bass Survival Guide
Now let's take a look at what are commonly referred to as box shapes. When we play patterns on the neck of the bass we refer to them as shapes. The outline for this particular pattern has a square shape that resembles a box. For example, let's say we have an A7 chord, the box shaped pattern would primarily include the notes A at the 5th fret of the E string, E 7th fret on the A string, the octave A on the D string, and the b7, G on the D string. Sometimes the 4, which is D, might be added. If you play those notes in succession you will see they form a square or box shape. There are many variations that can be played using this shape, but I will just give you a few examples. It's nice because it allows you to stay in one position on the neck also.
