Hi GMC!
Melodic playing is something that inevitably includes rhythmic playing, so, good melody, or melodic solo, is always built up on pauses or breaks during solo. This particular example, first part,  is mostly built on those pauses, in a way that pauses take more time than actual notes. The sole purpose of this short melody is to demonstrate application of breaks and their importance. Second part is built on particular pattern which is moved up the scale, and which contains few passing notes which are characteristic for jazz. Harmony is very basic, Gmaj7, Amin7 and D7, and scale used is G major.

Enjoy!
