Can You Organize All That?

[I really have to make this better. Not sure why it's grey, but I'll leave it that way until I produce a better version.]

Let’s make up some notation so we can be a bit more terse.  Let’s use majpent to mean the major pentatonic scale, minpent to mean the minor pentatonic, and blues to mean the blues scale, i.e. the minor pentatonic with the added tritone.  I’ll write R as the root of a general chord, and use R+s to represent the note gotten by adding s semitones to R, and R-s similarly.

Here’s a handy table summarizing the discussion of what pentatonic scale to play over each chord.

Chord	Scale to jam	Other Scales to try	For example, over this chord	play notes from this scale
R (major)	R majpent	R+5 majpent R+7 majpent	D	D majpent
R m	R minpent	aka R+3 majpent	Gm	G minpent
R m7	R minpent		Am7	A minpent
R m9	R+7 minpent		Fm9	C minpent
R 7	R majpent or    R blues	R+5 blues R+7 blues	C7	C blues
R 9 (w/dominant seventh)	R blues	R+5 blues R+7 blues	C9	C blues
R maj7	R+4 minpent	aka R+7 majpent R majpent	Dmaj7	A majpent
R maj9	R+7 majpent		Emaj9	B majpent
R sus4	R+5 majpent	R-2 majpent	Dsus4	G majpent
R 7sus4	R-2 majpent		D7sus4	C majpent
R add2	R majpent		Gadd2	G majpent
R 6	R majpent		A6	A majpent
R sus2	R+5 majpent	R-2 majpent	Ebsus2	Ab majpent

Here’s another table to help you add semitones:

R	R-2 (whole step down)	R+3 (minor third up)	R+5 (fourth up)	R+7 (fifth up)
C	Bb	Eb	F	G
C#	B	E	F#	G#
Db	Cb	Fb	Gb	Ab
D	C	F	G	A
D#	C#	F#	G#	A#
Eb	Db	Gb	Ab	Bb
E	D	G	A	B
F	Eb	Ab	Bb	C
F#	E	A	B	C#
Gb	Fb	Bbb	Cb	Db
G	F	Bb	C	D
G#	F#	B	C#	D#
Ab	Gb	Cb	Db	Eb
A	G	C	D	E
A#	G#	C#	D#	E#
Bb	Ab	Db	Eb	F
B	A	D	E	F#
