Many students have dizzying head movements when faced with the challenge of playing scales (or arpeggios) in contrary motion, (or from opposite directions starting at a keyboard mid-point)
To address a growing problem among students young and old, I devised ways to develop fluidity in this au contraire universe without a head trip.
Here’s the scale I picked: F minor. The FJH Scale Book sample page attached shows only the Harmonic minor in contrary motion, though I chose to focus on the natural form.
By the end of my instruction, I rippled through all three forms. (Pure, Harmonic, and Melodic)
