Major Scale (The Basics)

The major scale is made up of seven notes, if you're on the piano it's the easiest visual scale to play, start on the C note which is the first white key just below and before the first two black keys on the piano (these black keys are grouped in groups of two and three), just play all the white keys after that first one, you'll be going C D E F G A B C.

The space between each note might have a whole tone of distance or half a tone distance between them, where you have a whole tone of distance between two notes another one will fit in the middle, because we are talking about white keys another black key will fit between a whole tone. The basic formula for the major scale is 1+1+1/2+1+1+1+1/2.

There are only two half-tones in a major scale, between the third and the fourth degrees and between the seventh and the first degree of the next octave.
