Pentatonic
Scales
The Western, or
Classical, musical tradition uses the major scale as a building block.
It is made up of 7 notes. Other musical traditions use different building
blocks, including various scales.
One of these is
the Pentatonic Scale, which only has 5 degrees (Penta means 5 in Greek).
There are different
pentatonic scales. The most common to our ears is built by using only
these 5 degrees of the Major Scale: I - II - III - V - VI
By learning fingering
patterns for this pentatonic scale, you will be able to play a decent
solo over Rock or Blues changes.
Following are
two of the easier pentatonic scale fingerings (based on minor scale
fingerings previously introduced):

EXAMPLE: Starting
on the 5th fret, above left is C pentatonic scale (= A pentatonic
minor) ; above right is F pentatonic scale (= D pentatonic minor).
