B major Scale Explained: A Music Theory Guide

The B Major scale contains 7 notes: B, C#, D#, E, F#, G#, A#

You might see the scale written as starting and ending on a B and this can give the scale a ‘complete’ sound. The scale can also be repeating at higher or lower octaves and technically goes on forever. 

B Major is a diatonic scale, which means that it is in a key, in this case the key of B!

How Is The B Major Scale Created?

All Major scales follow a specific pattern of tones and semitones (steps and half steps). The tone pattern is:

Tone, Tone, Semi-tone, Tone, Tone, Tone, Semi-tone

If we take the start at a C and follow the pattern we will get the C Major Scale. To create the B Major scale, follow the tone/semitone pattern starting on the note B. 

 Whichever note you start on, you will always achieve the major scale starting on this note.
