A Discussion about A Major Pentatonic use with I, IV & V

A Major Pentatonic is a 5 note scale (hence pentatonic :-). It is the 1, 2, 3, 5 and 6th of the major scale. Since ther is no 4th, you will be a little hampered in finding the root of the IV chord in the scale itself.

Consider:

The A Major Pentatonic Scale (1, 2, 3, 5, 6). The notes are A B C# E F#
The I Chord is A (A, C#, E)
The IV Chord is D (D, F#, A)
The V Chorde is E (E, G#, B) - Note G# (7th) is not found in the scale


To the left are the arpeggios of each of the chords.
