My best recommendation on this site for piano lessons is Piano For All. Learn how to form major and minor scales in all keys. Locrian: A – B♭ – C – D – E♭ – F – G – A.Aeolian/Natural minor scale: G – A – B♭ – C – D – E♭ – F – G.Mixolydian: F – G – A – B♭ – C – D – E♭ – F.Lydian: E♭- F – G – A – B♭ – C – D – E♭.Phrygian: D – E♭- F – G – A – B♭ – C – D.Ionian/Major Scale: B♭- C – D – E♭- F – G – A – B♭.Learn more about the chords in the key of B flat major here. Chord vii – A diminished (Notes: A – C – Eb).Chord IV – E flat major (Notes: Eb – G – Bb).Chord I – B flat major (Notes: Bb – D – F).Now that we know the notes of the Bb major scale, let’s learn the triad chords in this scale/key and their notes. The finger numbers are as follows: Thumb: 1, index finger: 2, middle finger: 3, ring finger: 4, pinky (little) finger: 5. Finally, we move up a half step from A to Bb. Next, we move up one whole step from G to A. Next, we go up one whole step from Eb to F. Next, we move up a half step from D to Eb. Using this formula, let’s form a B flat major scale. To count up a half step (semitone), count up from the last note up by one physical piano key, either white or black. To count up a whole step (whole tone), count up by two physical piano keys, either white or black. “W” stands for whole step, and “H” stands for half step. They are based on the formula W-W-H-W-W-W-H. Major scales are formed by combining whole step and half step intervals. C is the supertonic of the B-flat major scale.Bb is the tonic of the B-flat major scale.Here’s a diagram of the Bb major scale on the bass clef. Here’s a diagram of the Bb major scale on the treble clef. My #1 Recommendation: Go here to learn about the BEST piano/keyboard course I’ve seen online. Major 6th – The 6th note of the scale is G.Perfect 5th – The 5th note of the scale is F.Perfect 4th – The 4th note of the scale is Eb.Major 3rd – The 3rd note of the scale is D.Major 2nd – The 2nd note of the scale is C.Tonic – The 1st note of the B-flat major scale is Bb.The relative minor of B flat major is G minor. This scale consists of the pitches B♭, C, D, E♭, F, G, and A. In this lesson, we learn how to play the B flat major scale.
