Below the examples included on the Useful Melodic Patterns for Bass Guitar book, for pattern number 04.
Here is the "easy" example, trying the pattern over the Bb Major scale on its third position, starting at the 8th fret (C) on the E string.
Also below, a video playing pattern 4, Bb major scale, fret 8
Now the advanced example, trying the pattern over the C diminished scale, starting at the 10th fret (D) on the E string.
Also below, a video playing pattern 4, C diminished scale, fret 10
And here a quick example about how to use our pattern number number 4 on a chord sequence that goes: Eb major 7(IV), D7 (VI's Dominant, here we took a harmonic license to play a chord that will help us "land" on the VI degree of the scale, which is G minor), and then G minor 7 (VI) over the Bb major scale (or G minor scale).
