For those studying “New Ears Resolution,” this blues lick is in the mixolydian mode. (See the chart showing the modes at the end of your book.) Try thinking of this melody first in mixolydian and then in ionian. Both sets of syllables are shown. Which ever set of syllables feels more comfortable to your ear, that is the set you should use. Try to play the melody as smoothly as possible, in order to realize the underlying swing. As with all exercises, start slowly and smoothly, gradually increasing the tempo. I play this at dotted quarter = 150.
