But hold on. Surely the flat 5 is the blue note? The Db in the G minor pentatonic? ??? The minor 3rd is just a standard "non-blue" part of the minor pentatonic. What am I missing? I never heard the minor 3rd referred to as a blue note before.
Singe there are so many scales and arpeggio's.... actually you can apply any of them as long as what you are doing is musical and/or fits the genre.
However, perhaps you meant something else, because Db is not a scale tone in the G Minor Pentatonic scale, as I know it.
The notes are.......
G Bb C D F G
And the Major Pentatonic is.........
G A B D E G
In the case of the Minor Pentatonic, yes you are correct in that you would not refer to the minor 3rd as a "blue note" .......because it is already flatted. However, if you were playing over a major chord using the Major Pentatonic scale but then switched to the Minor Pentatonic or even if you just played a minor 3rd, then you could refer to that min 3rd as a blue note.
What is meant by the term blue note in the case of the Blues Scale is because you are playing a
minor 3rd and/or a
flat 5 over a chord that has a
major 3rd and/or a
perfect 5th.
Blue note can also refer to the flat 7th but I left it out to try not be confusing, because a dominant 7th chord already has a flat 7 in it....the minor 7, an interval of 10 semitones. Since in blues we are dealing with dominant seventh chords almost all the time it seems silly to me to refer to it as the flat seventh.
However in jazz you might have the major seventh chord a lot and so if you played a minor (flattened) seventh against that....you would call it a blue note. Again, you would want to use it as a passing note or bend it so as to not sustain the note against the chord tone seventh which is a semitone above it....a minor second interval which depending how you use it is very dissonant.
I personally love sweet dissonance and love the minor second found in certain chords......but I digress.......
Basically think of a blue note as one that sets up a certain tension and then the release as it resolves to correct chord tone.
Blues is all about tension and release.
Anyway, I am no theory expert by any stretch of the imagination, this is just my understanding of things from years of application. Try not to get too hung up on what is a blue note though......... it is just a term used to explain or even justify certain scale notes. Just think of them as passing tones or whatever.
What is more important than any scale is the sound of what you are playing, how
what you are doing relates to the
chord tones or even the mood you are trying to create.
Personally, my favorite scale is the Lydian Auxiliary Diminished Blues Scale......... a fancy name for the scale, as it is referred to in George Russell's awesome book.....The Lydian Chromatic Concept of Tonal Organization. This scale is more commonly known as the Half Whole scale and contains both the minor and major 3rd, the flat 5th and the perfect 5th, the minor 7th, the sharp 9th and the flat 9th. I love the outside nature of this scale and have been using it as often as possible, since 1980 or so, being a staple in my improvisational palette.
However, while I find this scale great for Dominant 7th's.......if I am soloing over a straight blues I will avoid using it as it will take the sound of the improvisation
way out of blues and more into a jazz fusion thing........something that will cause a frown or three among blues purists.
In fact, this is the most common mistake inexperienced rock players make when jamming straight blues.......playing too many notes and the wrong notes. Nobody want's to hear how fast you are, whammy divebombs, chorus pedals or flangers etc and a thousand passing tones played at blinding speed, that say nothing, using a Dorian mode or what have you. LOL...."are you at the wrong jam? The rock jam is two doors down!"
Blues is all about feel and staying true to the form. Less is more. In a blues, one or two "right" note's can say so much more than a bunch of notes that are played merely for flash value.
If you are going to show some fast chops in a blues, you must set it up by playing a lot of traditional stuff.....showing that you know and respect the style and then fold in some fast runs. SRV, Albert Collins, Albert King, Buddy Guy........all great examples of this.
