1. 00:00 Introduction
Traditional opening vamp (4 bars x 2). A voice says “Lady Be Good?” 

2. 00:17 Chorus 1
(32 bars, 8 x 4.) Piano, bass, drum set; features Arnold Ross, piano.

3. 00:18 a
The Gerswhin melody at first, improvisatory thereafter.

4. 00:30 a
The chord progression of the song is maintained throughout: the listener's mind provides the melody, . . .

5. 00:43 b
as the pianist (and later, Parker) weaves the cool, complex bebop:

6. 00:57 a
thus something old, something new. 

7. 01:11 Chorus 2
Parker’s first chorus (32 bars). The sax somewhat wheezy.

8. 01:12 a
Only the first four notes are recognizable as Gershwin’s melody.

9. 01:25 a
In his first chorus he generally proceeds from syncopated figures in eighth-and quarter notes.

10. 01:39 b
Parker has the content of both 32-bars choruses in mind from the start. 

11. 01:52 a
. . .

12. 02:06 Chorus 3
Parker’s second chorus (32 bars). New background figure in trpt., sax.

13. 02:07 a
In bar 5 (02:14) he sets out in a flurry of arching 16th-note phrases . . .

14. 02:20 a
. . . with the phrase contours and content closely related to each other.

15. 02:34 b
. . .

16. 02:48 a
The closing motives refer to Parker’s opening gambit in chorus 2.

17. 03:03 (appl.)
(The other players go on to do their choruses.)
