Before we do that, however, let's talk about the major scale in general, to gain a clearer understanding of the theory behind it. A scale, in general, is a series of notes that are used together to create a specific sound or tonality. The major scale consists of seven different tones, each separated by either a half step or a whole step. A half step spans a distance of two frets on your fretboard, while a whole step spans three. The specific order of these intervals is what gives a major scale its distinctive sound.
All major scales utilize the same scale-building formula in their construction.
In other words, the major scale's sound is specifically created by a set order of half steps and whole steps. Every major scale, regardless of what note it starts on, has this same construction. They come in all shapes and sizes. The major scale, as we have seen, is composed of intervallic half steps and whole steps. Intervals generally have names that contain a numeric distance, such as a 2nd, 3rd, 4th, or 5th.
