Once you know the pattern of tones and semitones used to create the C major scale, you can build a major scale on any of the twelve notes used in music. It is important to memorize this pattern, which is shown here.
The semitones are always found between the 3rd and 4th, and 7th and 8th degrees of the scale. All the other notes are a tone apart.
By simply following the pattern of tones and semitones, it is possible to construct a major scale starting on any note. The scale will be named by the note it starts on. The following example demonstrates four more major scales.
Now that you know how major scales are constructed, try writing major scales built on the notes A, B, F#, Eb, Db and Gb. Some will contain sharps, while others will contain flats. Remember that the scale is named from its starting note and all you have to do is follow the pattern of tones and semitones.
