In plain words
Barry took this from Schoenberg, whose theory book, he said, starts with the human voice. Hit a C diminished seventh in close position: the top note is the soprano, then come the alto, the tenor and the bass. Barry’s own saying turns them into numbers: soprano is one, alto two, tenor three, bass four. He did the same in Tokyo, counting the voices from the top note down before calling drop 2.
Jazz theory, part 2: drop voicings5:316:07Piano workshop: upper structures and drop 29:3210:08
To drop a voice is to take it out of the close chord and play it an octave lower, leaving the others where they are. Barry would call drop 2, have the player go back to the close chord, call drop 3, go back again, then call drop 2 and 4. He said you have to know drop one, two, three and four, and added a ‘weird one’, drop 2 and 3, to hear what it sounds like.

For Barry, voicings like these, which he took from Schoenberg, were why he called jazz the continuation of classical theory. He treated them as basic equipment: in Bilbao he named a drop 2 in the middle of a borrowing lesson and told the players they should know how to do it, then went over which voice was soprano, alto and tenor, saying that mixing them up was the mistake. He also told a guitarist to practise drop twos and then take them up the scale.

How he said to practise it
Hit a C diminished seventh, then go through the drops one after another, returning to the close chord in between: drop 2, back, drop 3, back, drop 2 and 4. Try drop 2 and 3 as well, just to hear it.
Run each voicing up from the bottom, a note at a time, and bring it back down. Barry said you can make up a whole little song that way.

In Barry’s words
Each one plays from the moment he says it. Every other moment he teaches it is listed below.
Soprano is one, alto is two, [tenor] is three, bass is four.
So the first thing I’m going to say is drop two... go back, drop three... go back, drop two, four.
You gotta know about drop one, drop two, drop three, drop four, all this kind of stuff... Here’s a weird one, drop two and three.
See that there’s what you call drop 2. You should know how to do that.

Voicings: little chords, drop voicings and colour
- Idea
If you know all the big chords, Barry says, the small chords are already in your hands, yet many players cannot rip off simple small-chord playing because they never learned the little things. Most important is learning to play a sixth chord for a major chord; there is nothing wrong with that sound. He illustrated with We’ll Be Together Again, a song he says everyone should know.
- Exercise
In a workshop Barry had the players play a chord on the tonic of B-flat major and the two chords that follow it; some could not play those chords down by half steps and faked it. He asked who would notice that the first chord is made of two triads, then had them play a D minor triad and its next inversion, starting from the fifth.
- Exercise
Following Schoenberg, Barry names the voices of a four-note chord like a choir: soprano is 1, alto 2, tenor 3, bass 4. On a C diminished seventh, try drop 2, drop 3, drop 2 and 4, and even drop 2 and 3. Run each voicing up from the bottom, one note at a time, and you can make up a whole song with it. He says this is why jazz is the continuation of classical theory.
- Exercise
You play with your family first, Barry says. For a C seven he puts the E-flat triad above it (E-flat is in C’s minor-third family), then adds E natural right next to the E-flat. The E is what makes it sound like a dominant; without it you hear a minor seventh. Then let the voices move and resolve to F major.
- Idea
Two sixth chords work against E-flat major: E-flat six, on the tonic, and B-flat six, on the fifth. The B-flat six gives the major seventh and the ninth; the E-flat six gives the sixth and the tonic. For pretty chords, play one and add a single note from the other; adding a C struck Barry as almost unbelievably pretty. He adds that Bud Powell went further, using other sixes such as F six against the chord. You have to know the scale.
- Idea
While a pianist was comping on Misty, Barry stopped the playing: he wanted a plain D minor, not the augmented-ninth sound players habitually add to it. In a D minor you may put the E next to the F, but otherwise keep it simple. He also asked for an A7 with B-flat and E-flat added. The message is to choose each chord sound deliberately instead of reaching for the same altered voicing every time.
- Exercise
A pretty trick: play two tritones together, for example C, F, F-sharp, B, then move into the sus sound. Barry stresses that you must know the scale, not just the shape. To practise, move only the top and bottom voices, and also try it from the diminished.

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.

What his interviews, his students’ class notes and other teachers’ articles add.
Howard Rees’s glossary: the numbering works the same in any inversion, and the dropped note or notes go down an octave while the rest stay put. It also names two compound C6 shapes, ‘drop 1 with the 3 below’ and ‘drop 2 with the 4 below’; the second is the same as Barry’s drop 2 and 4.

Rees’s practice sheet orders the work: first the C major sixth-diminished scale in close block chords (C6 and B diminished alternating), then the same scale in drop 2, carried on up the scale and repeated in minor.

In Rees’s piano harmony course, drop voicings come as lesson 5, after the two sixth-diminished scales and half-step approaches, followed by minor sixth-diminished chords in drop 3.

Rees has readers run close voicings up and down the C minor 6 diminished scale and then drop or displace notes by an octave for open sounds. When borrowing a dominant root into a diminished voicing, he finds it works best where it makes a major seventh against the dropped note.

Masayasu Tsuboguchi says the block-chord scale needs drop 2 and drop 3 variants as well (for minor, lower the third), and that they take patient practice; he points to an Ellington horn riff in ‘Take the A Train’ as this kind of movement.

A Piano World member warns that a correct drop does not guarantee the sound: C6 in drop 2 with A at the bottom (A E G C) no longer sounds major, while drop 3 with G at the bottom (G E A C) does.
A jazzguitar.be member (christianm77): before borrowing diminished notes makes sense on guitar you need every inversion of major 6, minor 6, dominant 7, 7♭5 and diminished 7 in drop 2 and drop 3, which can take a few months.
A jazzguitar.be member’s ‘elevator’ scheme: harmonising a stepwise line all in drop 2 or all in drop 3 keeps the outer voices parallel, while changing the voicing type at each step makes them move in contrary motion.
