In plain words
Every sixth chord has a diminished chord that goes with it, and together they make its sixth diminished scale. Borrowing is putting one of those diminished notes where a chord tone was. Barry wrote a whole piece on the idea, named Borrowing at the suggestion of a blind student in his class at the Jazz Cultural Theater: instead of playing the notes of the sixth chord, you borrow the diminished notes. Listeners hear Chopin in it; Barry said he made it up, as a continuation of that tradition.

Diminished notes are restless. Barry said they ask to be moved, and they really do move: usually back to the chord tone beside them, though he also liked the idea of sending one on to the next chord tone. Even a major seventh chord, which we think of as complete, is really a sixth chord with one diminished note in it, and that note wants to go somewhere. Borrow two and both of them move.
Knowing this lets you take chances. Barry said he puts funny notes in because he knows which diminished goes with most chords: rather than play the same sound, he slips in some diminished notes and makes them go back. Most players, he said, don’t realise that what they heard was a diminished note going home, or that the same move can be made with two notes or with the whole chord.

Barry heard borrowing in classical music: what theory calls leading tones and appoggiaturas are really borrowed notes, and he described a chord in Chopin’s first Ballade as an E♭ chord made with a diminished note. In the borrowing class he also showed why one chord sounded right: it held an A♭ triad and a B triad, both from D7’s family of dominants.

Step by step
Find the sixth chord’s diminished: the diminished seventh a half step below its root. Together they fill the sixth diminished scale, so every chord tone has a diminished note on each side.

Play the chord, replace one chord tone with the diminished note next to it, then let that note go back. Barry’s example: on A minor 7, which is C6, borrow G♯ for the G and return to G.
Am7 (C6)- E
- G
- A
- C
G♯ borrowed- E
- G♯
- A
- C

- G
- A
- C
Do it for the other chord tones too, for example the diminished note above the E. A borrowed note may also carry on to the next chord tone instead of going back, as when G♯ moves up to A.
Hear the major seventh chord as a borrowed chord: a sixth chord with one diminished note in place of the sixth. That note is the one that wants to move.

Then borrow two notes, three, or the whole diminished chord, and bring them home together. Judge the results by ear: some combinations sound funny.

Borrowing works the other way round as well: on a diminished chord, borrow a note from the diminished a half step above or below and let it return. Howard Rees’ drop 2 example moves only the top note of D diminished over a B♭ bass, then resolves to E♭maj9.

A diminished note can sit in the bass. Over G7 Barry thought A♭ minor 6, and called the G in the bass a diminished note of that chord’s scale.

How he said to practise it
Learn the sixth diminished scales every way you can first; you have to know the scale all kinds of ways to borrow freely.
Introducing the sixth diminished scale20:1520:49Borrowed diminished notes on All the Things You Are2:28
Hold one chord and work through its notes: hit the chord, hit it with a borrowed note, take the note back, then try the next chord tone, and then two at once.
Take a standard such as All The Things You Are and borrow diminished notes in its chords as you go, including one in the bass.
In Barry’s words
Each one plays from the moment he says it. Every other moment he teaches it is listed below.
Diminished notes are weird notes. They say... move me somewhere... they really do... Even when you hit the major seven... A major 7th really is a 6 with one diminished note.
I know where diminished goes with most chords... I just take some chances, put me some diminished notes in there and make them go back.
So we took a six... And so instead of playing the sixth... you borrow the diminished notes.
We started saying leading tones... and all that kind of stuff. It’s really a borrowed note.

Introducing the sixth diminished scale
- 21:25
Diminished notes say ‘move me’; a major seventh is a sixth with one diminished note; two borrowed notes both move.
- 10:46
On A minor 7, borrow G♯ for G, hear the chord, then go back; G♯ could also go to A.
- 16:45
On C6, borrows the diminished note above the E, then has all three diminished notes move.
- 13:41
In the borrowing class: a chord holding A♭ and B triads sounds right because both are D7’s family.

From the lessons3 lessons, 10 points
Notes taken from Barry’s classes, each tied to the moment it comes from.
Diminished notes want to go home
- Idea
Diminished notes are restless, Barry says: they ask to be moved somewhere, and in practice they do move, to the neighbouring scale note. Even a major seventh chord, which we think of as complete, is really a sixth chord with one diminished note in it, the major seventh, and that note wants to move. If you borrow two diminished notes, both move. To handle all this you need to know your scale every possible way.
- Idea
Barry played a figure in which a diminished note resolves home to the chord, and said most players would not realise that is what it is. He then showed the same move with two diminished notes, and then with the whole chord, all going home. Knowing that these are diminished notes moving to chord notes lets you extend one small move into a bigger one.
Believe: a talk to musicians56:35
- Idea
Barry called himself an unknowing teacher who does things unknowingly and takes chances other players would not. Because he knows which diminished goes with most chords, he puts funny notes in: so as not to play the same sound, he takes a chance, puts some diminished notes in there, and makes them go back.
How to borrow
- Exercise
Play an A minor seven chord. For the G, borrow G-sharp, the diminished note: play the chord with it, then let it go back to G. Barry later extended the rule: for the E, borrow the diminished note above it, and so on, so each chord note can lean on the diminished note just above it before returning. He also thought a borrowed note could be sent onward instead, for example G-sharp up to A, and that it would probably sound good too.
- Idea
Why does borrowing sound right? Barry called the pianists over to look at a chord a student had made by borrowing: it contained an A-flat triad and a B triad. He asked for the related dominants, D7, F7, A-flat7 and B7, and pointed to those triads in the chord: that is why it sounds all right, because they are family.
- Exercise
When a student moved to F major, Barry pointed out that they had borrowed a diminished note, the C-sharp, and that the E could have been borrowed as well, or the whole thing. Judge such sounds by ear: some of these combinations sound funny.
Jazz theory, part 3: four dominants from one diminished10:4811:19
- Exercise
Barry played All the Things You Are while experimenting with diminished notes, borrowing them into the chords and lines as he went. To do this you have to know the sixth diminished scale and really practise it. He also had a student try putting the diminished note in the bass.
Borrowed diminished notes on All the Things You Are0:000:492:28
- Exercise
Borrowing also works on a diminished chord voiced in drop 2 (the alto dropped an octave). Starting from that voicing, Barry changes notes by borrowing to produce chords he says people have never played before. To work out what such chords look like, he suggests starting from the triads.
Jazz theory, part 6: every major sixth is a minor seventh4:045:216:157:41
Borrowing and the classical tradition
- Idea
Barry wrote a whole piece on borrowing: instead of playing the notes of the sixth chord, you borrow the diminished notes. A blind student in his class at the Jazz Cultural Theatre suggested calling it Borrowing. Listeners say it sounds like Chopin, but Barry made it up; he saw it as a continuation of the classical tradition.
- Idea
Barry believed the classical musicians knew the scales better than many great jazz players. What we label leading tones or appoggiaturas, he says, are really borrowed notes. His example is a strange chord in Chopin’s first Ballade, which he describes as an E-flat chord made with a diminished note.
In writing6 notes
What his interviews, his students’ class notes and other teachers’ articles add.
Jazz School Online defines borrowing both ways: a related diminished note in place of a note of a sixth chord, or a sixth-chord note in place of a diminished chord tone.
Rees builds a whole practice framework on a single diminished seventh chord: borrow from the diminished a half step above or below. Lowering a note gives one of four dominants, raising one gives one of four half-diminished II chords, and because they are related you can mix them freely.
Howard Rees with Ernie Rideout, Diminished Dimensions ¶7Howard Rees with Ernie Rideout, Diminished Dimensions ¶9Howard Rees with Ernie Rideout, Diminished Dimensions ¶10
Rees’ tune examples: Em7 voiced as G6 with F♯ and A borrowed from F♯ diminished; Dmaj7 as A6 with G♯ swapped in for A; over Fmaj7, a C6 with A♭ and B from B diminished. On dominants he borrows notes from the related dominants instead.
Rees’ online piano course takes borrowing in three steps: one diminished note added to a minor sixth chord, then three diminished notes in major and minor sixth chords, then a diminished note in different voices of the minor sixth.

A study-group member reports that Kingstone presents the ‘sixth on the fifth’ as borrowing: C6 over F6 sounds as Fmaj9 because C6 is F6 with two notes borrowed from its diminished.

Because each note of a sixth chord has notes of its diminished next to it, a scholar of Barry’s theory points out that borrowing works on every inversion of the chord.

Where the accounts differ1 point
Barry usually has the borrowed note go back home, though he also suggested sending it on (G♯ up to A). A forum member says that in Barry’s system borrowed notes need not resolve at all and can stand as new voicings.
