In this lesson, we learn how to play the B flat major scale. This scale consists of the pitches B♭, C, D, E♭, F, G, and A. Its key signature as two flats. The relative minor of B flat major is G minor.

B Flat Major Scale Diagrams
Here’s a diagram of the Bb major scale on the treble clef.
Here’s a diagram of the Bb major scale on the bass clef.
Here’s the Bb major scale on piano.
- Bb is the tonic of the B-flat major scale.
- C is the supertonic of the B-flat major scale.
- D is the mediant of the scale.
- Eb is the subdominant of the scale.
- F is the dominant of the scale.
- G is the submediant of the scale.
- A is the leading tone of the scale.
- Bb is the octave of the scale.
Major scales are formed by combining whole step and half step intervals. They are based on the formula W-W-H-W-W-W-H. “W” stands for whole step, and “H” stands for half step. To count up a whole step (whole tone), count up by two physical piano keys, either white or black. To count up a half step (semitone), count up from the last note up by one physical piano key, either white or black.
Using this formula, let’s form a B flat major scale. Our starting note is Bb. From Bb, move up a whole step to C. From C, go up one whole step to D. Next, we move up a half step from D to Eb. Next, we go up one whole step from Eb to F. From F, we move up a whole step to G. Next, we move up one whole step from G to A. Finally, we move up a half step from A to Bb.
B Flat Major Scale Piano Fingering:
- Notes: Bb, C, D, Eb, F, G, A, Bb
- Fingerings (Left Hand): 3, 2, 1, 4, 3, 2, 1, 3
- Fingerings (Right Hand): 4, 1, 2, 3, 1, 2, 3, 4
The finger numbers are as follows: Thumb: 1, index finger: 2, middle finger: 3, ring finger: 4, pinky (little) finger: 5.
Now that we know the notes of the Bb major scale, let’s learn the triad chords in this scale/key and their notes.
- Chord I – B flat major (Notes: Bb – D – F)
- Chord ii – C minor (Notes: C – Eb – G)
- Chord iii – D minor (Notes: D – F – A)
- Chord IV – E flat major (Notes: Eb – G – Bb)
- Chord V – F major (Notes: F – A – C)
- Chord vi – G minor (Notes: G – Bb – D)
- Chord vii – A diminished (Notes: A – C – Eb)
