Scale Degrees

  1. Bb is the tonic of the B-flat major scale.
  2. C is the supertonic of the B-flat major scale.
  3. D is the mediant of the scale.
  4. Eb is the subdominant of the scale.
  5. F is the dominant of the scale.
  6. G is the submediant of the scale.
  7. A is the leading tone of the scale.
  8. 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.
