The building blocks of western music.
The Major Scale is the foundation of all western music.
Arguably the most important scale in terms of understanding how music is written.
The scale consists of seven notes 1st , 2nd 3rd 4th 5th 6th and 7th and when we are describing other scales or referring to notes by numbers, we are always talking in relation to the Major Scale.
A scale formula is a pattern that describes the interval spaces between each note in the scale; the formula for the major scale is Tone, Tone, Semitone, Tone, Tone, Tone, Semitone. The formula helps us understand how a scale is created and helps us to work out and memorise the notes in the scale. We can visualise this by looking at a C Major scale on a keyboard and Guitar fretboard.
Each scale degree has a name given to it, these names become very relevant when analysing the harmony of music, they help us to understand the different functions and roles that notes and chords can have in a piece of music.
