This Tab illustrates how to play arpeggios with upper extensions. 

A triad is a basic three note chord. 
ex)1,3,5 (major) or 1,b3,5 (minor)

A Seventh chord is a four note chord with a seventh scale degree. 
ex) 1,3,5,7 (major 7)or 1,3,5,b7 (dominant 7)

Upper Extensions are any interval past the 7th of a chord:

2 = 9
4 = 11
6 = 13

What we're basically doing is taking any 7 note scale, and stacking them in 3rds instead of 2nds.

ex) c,d,e,f,g,a,b, (in 2nds) becomes c,e,g,b,d,f,a (in 3rds)

Let's use a couple different modes to make some of these arpeggios.
we will play all of these examples with a triplet feel on a G root.

Lydian:  1,2,3,#4,5,6,7 (2=9/#4=#11/6=13)
G Lydian:G,A,B,C#,D,E,F#

G major 7 (9,#11,13)

   |G B D F#A C#E C#A F#D B |
 G||——————————6—9—6—————————||
 D|o——————4—7———————7—4—————o|
 A|o————5———————————————5———o|
 E||3—7———————————————————7—||
   |1 + a 2 + a 3 + a 4 + a |

Dorian:  1,2,b3,4,5,6,b7 (2=9/4=11/6=13)
G Dorian:G,A,Bb,C,D,E,F

G minor 7 (9,11,13)

   |G BbD F A C E C A F D Bb|
 G||————————————9———————————||
 D|o————————7—10——107———————o|
 A|o————5—8———————————8—5———o|
 E||3—6———————————————————6—||
   |1 + a 2 + a 3 + a 4 + a |

Mixolydian:  1,2,3,4,5,6,b7 (2=9/4=11/6=13)
G Mixolydian:G,A,B,C,D,E,F

G Dominant 7 (9,11,13)

   |G B D F A C E C A F D B |
 G||————————————9———————————||
 D|o————————7—10——107———————o|
 A|o————5—8———————————8—5———o|
 E||3—7———————————————————7—||
   |1 + a 2 + a 3 + a 4 + a |

These are just a couple of the seemingly endless combinations of these arpeggios. 
Feel free to explore other modes using this formula. Make sure you practice these 
examples to a metronome slowly and then work your way up.

Please give me constructive criticism.
