3The half-step rules
Barry’s rules for adding half steps so the right notes land on the beat, starting with the dominant scale. They matter more than any named scale.

Idea 1 of 7
Coming out right: why half steps
Barry’s added half steps are not decoration: they are there so the line stays in rhythm and a scale tone or chord tone falls on the beat instead of the ‘and’. Chris says landing correctly while playing beautifully is most of what improvising needs, and the rules get you out of trouble when you find yourself in the wrong place. That is also why the same phrase needs different half steps depending on whether it starts on or off the beat.
Practise it: When a phrase lands on an off beat instead of a down beat, add a half step and check where you are in the scale.

Idea 2 of 7
The descending half-step rules for the dominant
Coming down a dominant scale in eighth notes from a beat, the half steps you add depend on the degree you start on. Odd degrees (1, 3, 5, 7) take one half step (between the tonic and the flat 7) or three (3 to 2, 2 to 1 and 1 to flat 7); even degrees (2, 4, 6) take none or two (2 to 1 and 1 to flat 7). The added notes keep the chord tones landing on the beat; Barry found the rules in Charlie Parker’s solos, and Chris calls them a puzzle piece that takes a while to get together.
Practise it: With a metronome (around 120), play both rules from every degree, each twice, in several guitar positions. Then use the phrases on the blues and the bridge of rhythm changes.

Idea 3 of 7
The half-step rules for the major scale
The major scale follows the same odd and even grouping as the dominant, but its basic half step falls between 6 and 5. From 1, 3, 5 or 7 you add one half step (6 to 5) or three (3 to 2, 2 to 1 and 6 to 5); from 2, 4 or 6 you add none or two (2 to 1 and 6 to 5). As on the dominant, the added notes keep the chord tones on the beat in descending lines.
Practise it: Descend from every degree of the major scale in time with each of its rules, then add running up from each degree before coming down.

Idea 4 of 7
The half-step rules on harmonic minor
Later in his teaching Barry applied the dominant-scale rules to harmonic minor. Where the rule asks for a half step that already exists as a whole step or more (tonic to major 7, or 3 to 2), you fill it with the scale note above instead: tonic, second, back to the seventh. The rules still put the right notes on the beat.
Practise it: Learn A harmonic minor over two octaves, then play each degree with its rules; take a few you like and make them your own minor riffs.

Idea 5 of 7
Which rule applies after a run or a leap
Barry extends the rules from plain scale runs to phrases. If you run up from a note and come back down, you use the rule for the note you started on; if you leap up a third or more, or come up a chord, the next note you hit going down decides; after a triad up, its top note lands on the beat and takes its own rule. These extensions give many more phrases from the same rules.
Practise it: From every degree, run up to each other degree and come back down with the starting note’s rule. Then do thirds, triads and chords up, each followed by the right rule.

Idea 6 of 7
No bebop scale: the half step is a placeholder
What most people call the bebop scale is just one of Barry’s half steps (tonic to flat 7 on a dominant, 6 to 5 on major), and Barry did not believe in bebop scales; late in his teaching he said the rules matter more than the scales. The added note is a rhythmic placeholder, so what counts is how many notes you add, not which ones. Chris puts other scale notes in the slot, such as the 6th where the major 7th would go or the 4th where the flat 3rd would go, and choosing your own filler notes is one way to sound like yourself while keeping Barry’s rhythm.
Practise it: Pick your own filler notes for one, two and three half steps, run them from every degree on the beat and on the ‘and’, and drop them into a tune such as Autumn Leaves or How High the Moon.

Idea 7 of 7
Triplets and the half-step rules
A triplet changes which rule applies. An eighth-note triplet between two scale notes shifts the line, so you use the rule of its middle note (the note the triplet goes to); a sixteenth-note triplet only ornaments a note, so you keep the rule of the note you started on. If a phrase no longer lands on the beat after you add a triplet, add or drop a half step.
Practise it: Put a triplet between tonic and 2, 2 and 3, and so on through the scale, applying the right rule each time. Then add an eighth- or sixteenth-note triplet to a phrase you already play on F7 and check that it still comes out right.
