Notice the pattern of black and white keys on the keyboard. The white key to the left of the two black keys is C, the next white key is D and the subsequent white keys are E, F, G, A, B, and then back to C again. The black keys make the sharps or flats for the white keys.
A scale is a set of notes played consecutively in ascending or descending order. Each key signature has its own sharps or flats. Beginning at the root, the formula for a major scale goes whole step, whole step, half-step, whole step, whole step, whole step, half-step.
Assign the number one to the root note, and number each subsequent note from two through eight.
Play first, third and fifth notes of the major scale simultaneously. This is the major chord.
