Question

What is the use of major scale in guitar​

Answer 1

Answer:

One of the first soloing concepts you encounter when learning how to play guitar is the major scale. This scale is used to solo over major family chords, especially tonic major chords, such as major, maj7, maj9, 6, and 6/9 chords.

Answer 2

Answer:

The major scale contains seven notes and has no sharps or flats when played in the key of C.

These seven notes can be written a number of ways, such as intervals:

R-2-3-4-5-6-7

Or you can think of them as specific intervals like this:

P1-M2-M3-P4-P5-M6-M7

In this case, each interval symbol would be:

P = Perfect Interval

M = Major Interval

You can also think of the upper notes as extensions, 9-11-13, rather than lower notes, 2-4-6. This means that you think of the scale with this pattern:

R-9-3-11-5-13-7

I prefer this way of thinking, as it helps you visualize the upper chord extensions.
