Major Scales ~ One octave,
contrary motion - B flat to E flat



This page will help you master the contrary motion one-octave major scales in the flat keys B flat to D flat - the scales in the 2H/SFG2 scale fingering group.

You will already have worked through introductory contrary motion page in C and the sharp keys to E major. Use the nav bar below to access other pages in the series.

The Scale Fingering Groups

Take a moment to look at the Scale Fingering Groups information - it will help you get an 'aerial view' of the scale fingering, rather than trying to remember the fingering key by key.

The twelve two-handed major scales fall into four groups:

  • '2H/SFG1*': C and sharp keys to E (RH SFG1 + LH SFG2)
  • '2H/SFG2': Flat keys B flat to D flat (RH SFG3 + LH SFG4)
  • '2H/SFG3': 'Odd Men Out' catch-up - F (RH SFG3 [4+4], LH SFG2) and B (RH SFG1 + LH SFG5 [4+4]). 
  • '2H/SFG4': the 'All-Blacks' (both hands SFG5) - D flat, F sharp (enh. G flat) and B majors.

*'2H/SFG' stands for "two-handed scale fingering groups" - the
groups of two-handed scales with similar fingering.

Here is the original (separate hands) Scale Fingering Group diagram for reference.

This page contains the '2H/SFG2' scales (RH SFG3 + LH SFG4) - flat keys B flat to D flat. (Flat key F major is an 'Odd Man Out' and comes with B on the 2H/SFG3 page.)

These scales are more challenging because, unlike the 2H/SFG1 scales, the fingering is no longer symmetrical - the thumb turns under at different times in the two hands.

Watch the video to see how best to understand the 2H/SFG2 scales.


The x5/x8 ConMo patterns

In this series of pages, you play these x5/x8 contrary motion (ConMo) patterns in all keys. You are hoping in the end to be able to play these patterns in any key.

B flat major

Have a good look at the key-specific keyboard (KSK) before you start.

B flat major has two flats - B flat, the tonic (from the F major scale - accidentals in key signatures are always 'carried over'), and the new E flat, on the fourth of the scale.


E flat major

Always bear in mind the logical build-up of the accidentals (black keys) as you move through the keys.

E flat major has three flats - the new A flat, on the fourth of the scale, plus B flat and E flat from the B flat major scale.


A flat major

A flat major adds the D flat on the fourth of the scale to three flats already in the key signature.


D flat major

D flat major has the G flat on the fourth of the scale, making it an all-the-black-keys major scale. (You'll also find it on the 'All Blacks' 2H/SFG4 page.)


Now go on to cover contrary motion in the F and B 'odd men out' majors, or use the series nav (below) to select another page.
