The following video shows how to learn and plug-in a jazz lick that outlines V7 resolving to I. With no trumpet lessons taking place due to the coronavirus outbreak, my son and I have been doing these kinds of jazz exercises during our daily practice time together.
There are two columns on this page. Work your way down the left column first, descending by tone; then, move on to the right column to cover the remaining six keys.
When memorizing the lick, I find it’s helpful to think in numbers, relating each note to its corresponding dominant chord. Therefore, I think of the line as: 3 5 b7 8 b9 #9 8 b7 going to 3 of the next chord. Understandably, my son hates thinking this way. He knows each line starts on the 3rd of the chord, and then plays it by ear. This is a good start.
The altered 9s (flat nine and sharp nine) create increased pull towards the resolution. For this reason, only plug this lick into spots where a dominant chord resolves to its one (V going to I).
For this video, the recorded accompaniment track was from Volume 54, Maiden Voyage, of Jamey Aebersold’s jazz play-a-long series.
If you play a bass clef instrument, here is a linked PDF document which has the above “plug-in jazz lick” written out in 12 keys, in both treble and bass clefs:
