L283 Bassline to Csus13 chord

FavoriteLoadingAdd to favorites YouTube Preview Image

When constructing a bass line to a Suspended chord (the 4th “suspended” interval replaces the 3rd ), its a good idea to use another scale than the obvious choice C mixolydian, to avoid emphasizing the major third because when Im playing the mixolydian scale the positions and scale patterns I use are so  – root, major third, fifth, seventh based – because im a bassplayer.  So to avoid that very “root position thinking” and at the same time getting fresh ideas i use a  “scale sibling” * -  another diatonic scale based on the same notes.

The Csus13, Csus9, Csus7.. is  normally a substitution for the dominant  C7, C9, C13… chord.

And that chord – the dominant 7th chord / mixolydian scale is derived from the 5th step of the F major scale (ionian)
So if we look at the diatonic scale/chord steps of the F major scale we get:
FMaj7 chord and the F ionian scale (steps 1, 2, 3 ,4, 5, 6, 7)

Gm7 chord and the G dorian scale (steps 1, 2, b3 ,4, 5, 6, b7) The scale I choose in the creation of this bassline

Am7 chord and the A phrygrian scale (steps 1, b2, b3 , 4, 5, b6, b7)

BbMaj7 chord and the Bb lydian scale (steps 1, 2, 3 ,#4, 5, 6, 7)

C7 chord and the C mixolydian scale (steps 1, 2, 3 , 4, 5, 6, b7)

Dm7 chord and the D aolian/natural minor scale (steps 1, 2, b3 , 4, 5, b6, b7)

Em7b5 chord and the E locrianscale (steps 1, b2, b3 , 4, b5, b6, b7)

The thing to notice that all 7 scales contain the same 7 notes (F, G, A, Bb, C, D, E) – its just the F major scale starting on the 7 different steps and they have these funny “greek” names Ionian, dorian etc

But you should actually just think of it as just a Major scale starting on different steps and since most of us have practiced the Major scale a lot ( i personally never got around to the locrian scale;-)), the thing is to recognize the different Major scale steps.

So here we have it

Csus13 substituting C13, see as 5 step of F major, so then when you improvise you can use all the before mentioned scales derived frm th F major scale

Here im playing ogf the Gm7 dorian scale, the 2nd step of the F major scale – im still emphasizing the root note C but otherwise looking at as a G minor dorian scale

That forces me to invent new fresh patterns since i see the same notes in a new fashion.

Heres soem of the scale choices i frequently use could use when playing over dominant sus 7:

The root scale of course – C mixolydian
G dorian minor, G minor pentatonic, D aolian minor , D minor pentatonic, Bb Major lydian,  Bb major pentatonic,,,,

The pentatonic scale are interesting because you allready know that scale so well – try and take one of your blues pentatonic licks and play over this backing track – look above for hints of which you could try

AND REMEMBER ITS THE SAME 7 SCALE NOTES (F, G, A, Bb, C, D, E ), you just view it from different “angles of the fretboard” and trick your brain into playing new awesome licks;-)

* “Scale sibling” is my own expression for a scale derived from the “Mother” of all scales on the western hemisphere – the Major scale)

Ive done the backing track in Mac Garageband using a standard drumloop and playing a Squier Stratocaster;-)

Hi!

You’re my eye-opener! I’ve got this theory a while ago but I never get the function of it. I just thought why call it with those weird names, just say it’s a major scale started from .. Now i know,, it’s just like that lol!

But how did you studied it? Just sat in your room and puzzled which scales fits which chords?

Most of the time when a pianist is playing chords, I’m playing the root scales and that’s just one or two scales. Because there following more chords and my brain can’t handle that yet haha. On this one there is just one chord so that makes it a looot easier for me.
Is it possible for you to make a video like this but with more chords, and maybe more scales? Really want to see that to understand it a little bit more.

Thank you very much!:).

2rad: Hello Marlow, I have sent you a gift for my yearly or so contribution to your very much appreciated efforts. There is a nice little box on its way from Canada.

MarloweDK: Most notation programs do that, i use guitar pro and sibelius ( for nicer notation)

grunz7: Hi - I am looking for a notation programm that can also handle deadnotes. Maybe even open source? Can you suggest something?

MarloweDK: My Slap bass app is now updated to iOS 7

MarloweDK: Den er opdateret nu:-)

MarloweDK: Den er sendt til apple , så det er inden for denne uge tror jeg, det har varet noget tid pgr af en tredjeparts plugin.Tak:-)
