Drop voicingsDrop 2, drop 3, drop 2 and 4 (choir numbering)

Barry numbered the four voices of a close chord like a choir, soprano 1 to bass 4, and had players drop one or two of them an octave: drop 2, drop 3, drop 2 and 4. He treated this as classical knowledge jazz needs.

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.

Barry also used ‘drop’ in another sense: lowering one note of a diminished chord a half step, Schoenberg’s rule that turns it into a dominant. That is a different idea (the family of dominants), not a voicing.

Step by step

  1. Play a four-note chord in close position and number its voices from the top: soprano 1, alto 2, tenor 3, bass 4.

  6. Then put a drop voicing on every chord of a sixth-diminished scale, so the top note walks up the scale while the chords alternate between the sixth chord and the diminished chord.

How he said to practise it

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.

Voicings: little chords, drop voicings and colour

  1. 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.

    Small chords, not big ones1:402:132:49

  2. 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.

    The 1998 workshop, part 145:2746:3747:1249:56

  3. 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.

    Jazz theory, part 2: drop voicings5:316:077:107:54

  4. 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.

    Jazz theory, part 3, with score9:169:5010:30

  5. 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.

    Two sixth chords against a major key0:040:382:203:59

  6. 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.

    Feeling the ‘and’5:205:56

  7. 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

  1. 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

  2. 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.

  3. 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

  4. 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.

  5. 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.
