Chords fitting over a scale, E-shape scale & other questions relating to the music theory course

Hi, so I don’t have any background in music, I’ve started the course, module 1.
I thought it best to start to learn some music theory, so I purchased the course.
I am having some trouble with some of the terminology.
For example, when Justin says “ this chord fits over the scale perfectly, what does that mean exactly.
I can see the G chord corresponds to 3 of the places on the scale, but is that the only relationship?

I was also wondering why Justin says, at the beginning of the lesson of the major scale pattern 1 “it’s in the key of G, but is often referred to as the E shape”.

Thank you.

Good on you - it will all come to you and you will be able to answer your own questions in time.

I’m not sure which lesson this is from.
Is it concerning the G major scale?
If yes then the G major scale and the G major chord are entirely connected to one another. The chord is the tonic chord. It is the home chord. It is the I chord. It is the chord whose root note is the root note of the scale.

G major scale
G, A, B, C, D, E, F#
G major chord
G, B, D
G major scale (again)
G, A, B, C, D, E, F#

G is the root note so it is the G major scale and therefore the key is fixed from that root note.
It is the E-shape within a system called CAGED whereby there are five and only five different patterns with which a major scale can be played on a guitar neck. This pattern is the E-shape and is conventionally taught first so CAGED could equally become EDCAG but that is a less catchy name.

I will leave you to seek and find the connection here … look for something the scale pattern and the chord shape have in common.

I hope that helps.
