In music, the sixth mode of the major scale, with the following half step/whole step progression: W-H-W-W-H-W-W.
Identical to the natural minor scale.
For example:
  • C Aeolian contains the notes C D Eb F G Ab Bb
  • A Aeolian contains the notes A B C D E F G
  • F# Aeolian contains the notes F# G# A B C# D E
Two ways of playing the G Aeolian scale in guitar tablature form:
Three notes per string:
e|--------------------------------5-6-8-|
B|--------------------------4-6-8-------|
G|--------------------3-5-7-------------|
D|--------------3-5-7-------------------|
A|--------3-5-6-------------------------|
E|--3-5-6-------------------------------|

Staying in (roughly) the same neck position:
e|------------------------------3-5-6---|
B|------------------------3-4-6---------|
G|------------------2-3-5---------------|
D|--------------3-5---------------------|
A|--------3-5-6-------------------------|
E|--3-5-6-------------------------------|
