In plain words
In Barry’s class every scale runs from the tonic to the seventh, never tonic to tonic. ‘Up’ means start on the tonic and run up to the seventh. ‘Down’ means start on the seventh and run down. ‘Up and down’ means tonic up to the seventh and back down. The seventh is the major seventh in a major scale and the flat seventh in a seven (dominant) scale. Even on the eight-note diminished scale, up and down goes only to the seventh note.

A scale is named after a chord: ‘B♭ major’, ‘F7’, ‘F minor’. Barry reminds the class that every seventh scale is a major scale: the F7 scale is the B♭ major scale run from F. With these words a whole tune becomes a chain of scales. In one class a B♭ blues is recited as B♭7 up, E♭7 up, B♭7 up and down, and so on, and Barry says he expects everyone to know that basic blues.

‘To the third of’ names the landing note: keep running and finish on the third of the next chord. In Barry’s outlines the next chord is often a dominant whose third lies a half step above the tonic of the scale you are running, so the run ends on that note instead of the tonic: B♭ major to the third of G ends on B, E♭7 to the third of C ends on E.

A ‘chord’ is four scale notes, each skipping one note, played as a line: a ‘chord up on the third of B♭ major’. An ‘arpeggio’ is a triad with its bottom note repeated on top, like D F A♭ D in B♭7; a ‘triad’ is the bare three notes. Barry preferred to name these by the degree they start on rather than by chord symbol, because names confuse. Chris Parks: what most players call a G7 arpeggio is, for Barry, a chord.

‘Down to the third of’ a chord: run down and land on that chord’s third. Here, from Barry’s Indiana outline, the B of G7 replaces the scale’s own tonic B♭.

‘Chord on the’ a degree: the four notes built up from that degree, skipping one scale note each time, played as a line up or down. ‘Arpeggio on the’ a degree: the triad from that degree with its bottom note repeated on top.

Put the words together into a call: where to start, what to add, which way to run, where to stop, what to do next. Barry’s own example: start on the third of B♭7, put one half step between the tonic and the seventh, run down the scale to the third, then play a chord up.

How he said to practise it
Play a call the moment it is given, in time and in eighth notes. Barry counted off straight after each call, stopped the class when it was wrong, and insisted on eighth notes rather than quarter notes.

Write tunes out as scale calls. Barry dictated Indiana as a chain of ‘up’, ‘up and down’ and ‘down to the third of’, had the B♭ blues recited the same way, and wanted players to keep these outlines in their own books.

In Barry’s words
Each one plays from the moment he says it. Every other moment he teaches it is listed below.
Every scale you play, you play from [tonic] to major seven... If I say up, you just go up. If I say down, you just go down from the seventh.
We played D, F, A-flat, and D. That’s a diminished arpeggio.
I even hate to call the chords by name on the scale, you know, because then you get confused... so you’d play a C-7 and you wouldn’t even know what it was.
Every 7th scale is a major scale, right? F 7 scale is B-flat major scale.

How Barry calls a scale
- Exercise
When Barry calls a scale, never play it from the tonic to the tonic an octave up. A major scale runs from the tonic up to the major seventh; a dominant seventh scale runs from the tonic up to its (flat) seventh. ‘Up’ means ascend only. ‘Down’ means start on the seventh and descend. ‘Up and down’ means go from the tonic up to the seventh and back down. Try his drill: B-flat major scale, up and down.
Practising the blues with the horns, part 10:00
- Idea
Barry said everything he taught was based on logic, which is why he felt no music teacher could face him down. He dismissed the common habit of describing scales as half-step/whole-step patterns, and provocatively claimed that the major scale handed down to us is wrong: it has eight degrees, he said, and should have nine.
In writing5 notes
What his interviews, his students’ class notes and other teachers’ articles add.
Alan Kingstone gives Barry’s wording for B minor 7♭5 to E7: ‘down the G7 scale from the seventh to the third of E7’ for a one-bar phrase, ‘up and down the G7 scale to the third of E7’ for two bars. He adds that Barry never speaks of Dorian, Mixolydian or avoid notes.

Galliano’s notes map these calls onto bar lengths: one bar on a chord, run its scale from the root up to the seventh; two bars, up to the seventh and back. When a I chord and a VI7 take a bar each, run the I scale to the third of the VI, a half step above the I’s root.
Galliano’s notes keep Barry’s split: scales practised ‘in chords’ means four-note seventh shapes on each degree, while the ‘important arpeggios’ are octave triads, on a dominant built on the root, fifth and seventh (on C7: C major, G minor, B♭ major).

Tom Cleary’s class calls the minor ii-V scale for Gm7♭5 to C7 ‘E♭7 up and down to the 3rd of C’, a seventh scale from a major third below the ii. Ending the downward half on the note a half step above the scale’s root (here E) outlines a diminished chord that works as the V chord without its root.

Christian Miller recalls that in workshops a standard was first covered with scale outlines, 1 to 7 and 1 to 7 and back, before Barry dictated a line and explained how he built it; by the end of the session the class had a bebop chorus on the tune.

Where the accounts differ1 point
Students’ usage drifts. A forum member’s 2016 outline of Barry’s scale practice called four-note chords ‘arpeggios’; in 2019 the same member wrote that Barry calls triads arpeggios and four-note shapes chords, which matches Chris Parks and Barry’s own D F A♭ D example.
