Watch the Major Scale Form II 4 online guitar lesson by Brad Carlton from Guitar Lab: Caging ii V I
This lesson focuses on playing and hearing the F Ionian mode in third position utilizing scale form II of the F major scale. Diagram 29 shows the arpeggio for the I chord in the key of F. This chord is an F and is played with the D form out of the CAGED system. The remaining black degrees in this diagram form the F Ionian mode.
Example 23 demonstrates an exercise in which the lower voice is the root of the F chord and the upper voice is a descending F Ionian mode.
