Английская Википедия:Bird changes
The Blues for Alice changes, Bird changes, Bird Blues, or New York Blues changes, is a chord progression, often named after Charlie Parker ("Bird"), which is a variation of the twelve-bar blues.
The progression uses a series of sequential ii–V or secondary ii–V progressions, and has been used in pieces such as Parker's "Blues for Alice". Toots Thielemans's "Bluesette",[1] Freight Trane written by pianist Tommy Flanagan, and Parker's "Confirmation"[2] also have similar progressions.
Structure
A simple blues progression, in C, is as follows:
- <score sound="1">
{ \new ChordNames \with {
\override BarLine #'bar-extent = #'(-2 . 2) \consists "Bar_engraver"
} \chordmode {
\override Score.BarNumber.break-visibility = ##(#f #f #f) \set Score.tempoHideNote = ##t \tempo 1 = 60 c1:7 | c:7 | c:7 | c:7 | \break f:7 | f:7 | c:7 | c:7 | \break g:7 | f:7 | c:7 | c:7 \bar "||"
} } </score>
A typical blues progression in jazz, in C, is as follows:[3]
- <score sound="1">
{ \new ChordNames \with {
\override BarLine #'bar-extent = #'(-2 . 2) \consists "Bar_engraver"
} \chordmode {
\override Score.BarNumber.break-visibility = ##(#f #f #f) \set Score.tempoHideNote = ##t \tempo 1 = 60 c1:7 | f:7 | c:7 | c:7 | \break f:7 | f:7 | c:7 | e2:m7 a:7 | \break d1:m7 | g:7 | c2:7 a:7 | d:m7 g:7 \bar "||"
} } </score>
The Bird Blues progression, in C, is as follows:[4]
- <score sound="1">
{ \new ChordNames \with {
\override BarLine #'bar-extent = #'(-2 . 2) \consists "Bar_engraver"
} \chordmode {
\override Score.BarNumber.break-visibility = ##(#f #f #f) \set Score.tempoHideNote = ##t \tempo 2 = 60 c1:maj7 | b2:m7.5- e:7 | a:m7 d:7 | g:m7 c:7 | \break f1:7 | f2:m7 bes:7 | e:m7 a:7 | es2:m7 aes:7 | \break d1:m7 | g:7 | c2:maj7 a:7 | d:m7 g:7 \bar "||"
} } </score> In roman numeral analysis, this is represented by
IM7 viiШаблон:Music7 III7 vi7 II7 v7 I7 IV7 iv7 Шаблон:MusicVII7 iii7 VI7 Шаблон:Musiciii7 Шаблон:MusicVI7 ii7 V7 IM7 VI7 ii7 V7
This can be viewed as a cycle of ii–V progressions leading to the IV chord (F7 in the key of C major), and the tritone substitution of the dominant chords leading by half-step to the V chord (G7 in C).[4]
