7 chAnGinG eb to D
Here Carl shows how, by changing the Eb note in the melodic idea to D natural, the lick is now perfectly suitable for Bb7, creating the chord degrees: b7-5-b7-3-5. These clearly imply a Bb7 chord. In bar 3 below, he shows how it could be played in both ascending and descending form, and even extended downwards to a low D natural. Again, storing away ideas that can be used as is, or tweaked to fit other musical situations - chords, etc.
