In plain words
Barry’s name for it was mirror image: doing the same thing with each hand. He showed it as one more way to practise a scale, alongside thirds and the rest, since a scale should be practised any way you can find. When a student in Rome said the left hand could not manage the three-note figures, he insisted it should: anything one hand does, the other can do, because you have the mirror image.

The basic exercise is a scale in contrary motion from middle C: both thumbs on C, the right hand going up while the left goes down, then back together. Barry set it on the sixth diminished scale, major and then minor, called pianists up to play the D♭ and D scales this way, and said guitarists can do it too. With a young player who had just played the chords, he said the first thing he would have her do is go contrary.

Then fill it in. As the two outer voices spread from the unison, add the chord notes between them. In one class he had students go out with both hands, then play three notes of the major sixth chord, then all four notes of the diminished chord, then G with C, E and A, and said that doing scale things like this is what music is about. From the notes of a C6, he showed, going contrary makes a beautiful little move.

Barry heard the same idea in the music he loved. Going through a Chopin piece, he pointed out a passage that works as a mirror, one side the opposite of the other, and called it pretty.

Fill it in. At each step add the notes of the same chord that lie between the two hands. The hands always land on the same kind of note, both sixth-chord notes or both diminished notes, so the filled-in chords take turns: sixth chord, diminished chord, sixth chord.

Vary it, as Howard Rees’s worksheet does: start with the hands apart and move them in towards each other, or play the right hand in thirds or fourths with the left hand under it, moving with it or in contrary motion.

How he said to practise it
Whatever figure you practise in one hand, practise in the other as its mirror image, until the left hand can do everything the right can.
The 2016 workshop, part 3: Monk’s tunes, not his style25:2526:04
Practise a scale contrary, then fill it in; then try it in thirds and as a mirror image. Barry’s advice was to find every way to practise a scale.
Take every sixth diminished scale through contrary motion, not just C. Barry wanted a class to know all of them by the next day, and had pianists play them contrary and then filled in.
In Barry’s words
Each one plays from the moment he says it. Every other moment he teaches it is listed below.
Go contrary from middle C. You’ve got to use both hands. Put both fingers on middle C. Go contrary. Back together. And you can do that on your guitar too.
That’s using a mirror image, right? You know, doing the same thing with each hand.
You should be able to do all that... Anything you do, you do it. Because you got the mirror image.
Sometimes I make people practice like this. Say you know the scale in C. You should practice the contrary. Then you fill it in.

Two hands together: small chords blended between the hands
- Exercise
Give the left hand the same facility as the right. When a student practises small three-note figures, Barry insists the left hand must be able to play them too. He uses the mirror image between the hands: whatever one hand does, the other does in mirror form, so you can practise this kind of figure in either hand.
The 2016 workshop, part 3: Monk’s tunes, not his style22:5724:4825:25
- Idea
Barry contrasts pianists who play one note at a time in one hand with his own way of playing, which is combinations: the two hands working together. He says he does not know where one-hand piano came from, and demonstrates the two-handed sound on In Your Own Sweet Way, a tune from the previous day’s class, pointing out the diminished notes in it.
- Idea
No chord should be played with the left hand alone, Barry insists; you have to learn chords played with both hands. He was struck to find piano students who had never played a certain chord in their lives, which he blamed on their keeping the left hand up high because, they say, the low register belongs to the bass.
Eyes of the Masters: the first progression2:28Believe: a talk to musicians16:43
- Idea
Play small chords, not big ones. Barry says that at every school he has visited (he names North Texas, Berklee, Boston Conservatory, McGill, Concordia and schools abroad) pianists play big chords. A school, he says, should be dedicated to small chords, with nobody playing one-note melodies in the right hand: the chords should be blended across both hands. He saw this clearly when an older student in his class played a song as a blend of the two hands. In another class, too, he reminds players that being beboppers doesn’t necessarily mean big chords up at the top, just little ones.
Small chords, not big ones0:331:05Passport: teaching a blues by ear7:01
- Exercise
Practise drop voicings on the diminished seventh chord. Following a theory book that begins with the human voice, Barry names the four voices of a C diminished seventh chord from the top: soprano (1), alto (2), tenor (3) and bass (4). Then work through the drops: drop 2, drop 3, drop 2 and 4, and even the odd drop 2 and 3. Run a voicing up step by step and bring it back down, and you can make up a whole little song from it.
Playing the scale of chords
- Exercise
Voice a C chord with C in the left hand and G, B and E in the right. First move it up the ordinary C major scale, then up the sixth diminished scale. The rule students keep forgetting: after G comes A-flat, every time, and after A-flat comes A. When a student got the order wrong or failed to move a voice, Barry stopped them and made them go back to the first chord.
- Exercise
Try harmonising a melody with the scale of chords. Barry had a student harmonise a phrase of My Funny Valentine with chords from the sixth diminished scale, starting from the fourth degree and moving down the scale. The chords are pretty and quite different from what you get from the major scale, and intervals of a fourth appear in the voicings, which he called hip.
- Idea
Once you know the sixth diminished scale, Barry says, you can do things you never did before without worrying. Working in E-flat six diminished, he says he can do anything he wants: he points out diminished notes and makes notes catch up, and it works as long as he ends it properly.
In writing5 notes
What his interviews, his students’ class notes and other teachers’ articles add.
Howard Rees suggests contrary motion as an easy way into moving voicings along the sixth diminished scales: start on a unison, step outwards, and fill in between the outer voices. The chords always alternate major sixth and diminished seventh, which he hears as a I to V motion.
Howard Rees, Evolutionary Voicings, Part I: Barry Harris Keeps Things Movin’ ¶41
Rees’s worksheet orders the practice: the C6 diminished scale in unison in both hands, then in contrary motion, then with the hands starting apart, then with the right hand in thirds or fourths over a left hand moving with it or in contrary motion. Each is also to be done on the minor sixth diminished scale.

The Workshop Video workbooks give contrary motion its own place: Part 1’s chapter on moveable chords includes the C6 diminished scale in contrary motion, and Part 2 sets contrary-motion exercises on four scales, the major and minor sixth diminished and the C7 and C7♭5 diminished scales.

Rees applies it to a tune: in bar 1 of Body and Soul he harmonises the melody with contrary motion on the D major sixth diminished scale, and does the same in bar 5 on the D minor sixth diminished scale.
A guitarist on jazzguitar.be explains Tommy Echols’s ‘floors and elevators’: from a unison, top voice up and bottom voice down, filling the middle from the sixth or diminished chord. Staying on one floor moves the outer voices in parallel; taking the elevator moves them in contrary motion, and either way the sixth and diminished keep alternating.
