Scales And Chords
C7#9 chord
This chord is built with :
- Root (C)
- Major third (E)
- Fifth (G)
- Minor seventh (Bb)
- Sharp ninth (D#)
Here are three common C7#9 guitar positions.
The last one (on the right) is used by Kenny Burrell in "Chitlins con carne", it has no root (C) and no major third (E).

C minor pentatonic scale
As its name implies the minor pentatonic scale contains five notes, it is mainly played by Kenny Burrell in Chitlins con carne over C7#9 :
- Root
- minor third
- perfect fourth (eleventh)
- perfect fifth
- minor seventh.
That gives the following notes in the key of C : C-Eb-F-G-Bb.
What we can deduce is that the C minor pentatonic scale contains notes that belongs to the C7#9 chord : C is the root, Eb is the #9, F is the fifth and Bb the minor seventh of C7#9.
C minor blues scale
The minor blues scale contains the same notes as the minor pentatonic scale, including a passing tone (Flat fifth) also called "Blue note". It is made up with six notes :
- Root
- minor third
- perfect fourth (or eleventh)
- Flat fifth (blue note)
- perfect fifth
- minor seventh
We get this in the key of C :
C-Eb-F-Gb-G-Bb
Please note that there are three types of minor blues scales as explained in this lesson
