The key is the tonal center of the song or the home tone. Each key has a series of notes called a scale that corresponds to that tonal center. The scale starts and ends on the tonal center. The scale is made up of a combination of whole and half steps. The pattern of whole steps and half steps is what gives a type of scale (major, minor) its characteristic sound. For each scale type the pattern is always the same regardless of the key. See below for more information.
