In plain words
As Chris Parks explains Barry’s vocabulary, an arpeggio is a triad with its bottom note repeated an octave up, while the four-note stack most players call a C7 arpeggio is, for Barry, a chord; the arpeggio up from C is C E G C. In a 1998 Hague class Barry had the players run an arpeggio from each degree of the B♭7 scale in turn, and stopped them on the diminished one that turns up on the third, D F A♭ D.

Of all the arpeggios on a dominant scale, Barry singled out three: the ones on the tonic, the fifth and the seventh. In B♭7 these are B♭ major, F minor and A♭ major. He disliked calling them by chord names, because names confuse; he would rather you thought of a chord simply as scale notes with one skipped between each, without knowing what it was called.

The one on the seventh interested him most. It is an A♭ major arpeggio, but inside B♭7 it means B♭7, not A♭ major: if you run notes between its bottom and top A♭, they are B♭7 scale notes, so D rather than D♭. By contrast, an E♭ arpeggio used inside A♭ major is filled in with A♭ major notes.
The minor arpeggio on the fifth stands on what Barry called the important minor, the minor that is always found on the fifth of a dominant. Beyond the three, he pointed to two more sounds inside the dominant scale: the augmented arpeggio, very important when the dominant resolves, and the diminished from the third (the next idea).

To run notes between an arpeggio’s notes, use the scale the arpeggio is standing in, here the dominant scale, not the arpeggio’s own major scale.

How he said to practise it
Run an arpeggio up from each degree of a dominant scale in turn, as Barry’s class did on B♭7.
The 1998 workshop, part 136:17
Invert an arpeggio so the same note is at the top and the bottom, and play each inversion up and down; Barry had the class do this with the one on D in B♭7.
The 1998 workshop, part 137:49
Treat triads and arpeggios as basics to know cold, all your minor arpeggios and diminished chords included. Barry said these are the things players hate most, and that players learn by taking the basic things and making little things up from them.

In Barry’s words
Each one plays from the moment he says it. Every other moment he teaches it is listed below.
There are three important arpeggios with a dominant seventh scale. One is the tonic, one is the fifth, and one is the seventh.
B flat major arpeggio on the tonic, the F minor arpeggio on the fifth, the A flat major arpeggio on... the seventh.
If you had to run the notes in between, you’d have to run B flat seven notes in between that A flat and that A flat.
I hate to call them by name, see. I even hate to call the chords by name on the scale, you know, because then you get confused.

Arpeggios inside the dominant scale
- Idea
A dominant seventh scale has three important arpeggios, built on the tonic, the fifth and the seventh. For B-flat 7 these are B-flat major (tonic), F minor (fifth) and A-flat major (seventh). Barry found the one on the seventh the most interesting: it is an A-flat major arpeggio, but it still means B-flat 7, so if you fill in between its notes, use B-flat 7 scale notes, not A-flat major. Another pretty one to add is the augmented arpeggio, which he called very important for going home (B-flat 7 resolving); the diminished can be used too.

Transcribing the workshop DVDs, Vera Marijt notes that Barry keeps coming back to the three important triads on the dominant, and that his arpeggio exercises are meant to be applied to minor and augmented arpeggios too.

A member analysing Barry’s solo on ‘You Can Depend on Me’ with Sonny Stitt finds the phrase opening on the important arpeggio on the ♭7 of the dominant, entered from a half step below its root, then running down the scale; he reckons it is the one Barry plays most.

Where the accounts differ1 point
Mariano Abello’s handout uses ‘arpeggio’ for four-note shapes on the tonic, third, fifth and ♭7 of F7 (F7, A half-diminished, C minor 7, E♭ major 7). In Barry’s terms, as Chris Parks reports them, those are chords; Barry’s own arpeggio is a triad plus its octave (D F A♭ D), and his three important ones sit on the tonic, fifth and seventh, without the third.
