Where do I start when learning the B flat major scale?

The best place to start when thinking about scales is the circle of fifths.

To know more about the circle of fifths, make sure to check out all the information and exercises on this website about the circle of fifths if you are not completely sure on what the circle is and how it works.

The starting point on the circle of fifths is C major because there are no sharps or flats within this scale.

Bb major is the second scale to the left of C major, on the circle of fifths, meaning that it will have two flats. These flats are B flat and E flat.

As mentioned in our C and F major blogs, major scales always follow the same pattern of tones and semitones (whole steps and half steps)

This is as follows:

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

Whole Step, Whole step, half step, whole step, whole step, whole step, half step

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

The Bb major scale is simply this pattern but starting on the note Bb.

Rather than writing the flat signs on the individual notes, we can now make use of the key signature. Because every single B and E are flat, we can simply write this at the start of the piece! 

Above we have written one octave of Bb major. It is important to note that this can also be written an octave higher or even an octave lower!

Scale degree names in B flat major

As with all scales, each note name is not only given a letter but it is also labelled with a number. We call this number a scale degree.

The scale degrees are as follows:

Bb – tonic

C – Supertonic

D -Mediant

Eb – Subdominant

F – dominant

A – leading note/leading tone

Bb – tonic

If we say that a piece of music is in the key of B flat, this means a few things:

  • The tonic (or home note) of the piece will be Bb! This note will sound the most stable in the whole piece.
  • The piece will use notes only from this scale, these could be in any octave. 
  • The chords used will be those chords that are in Bb major
