Notice how the motifs start developing here. Including motivic development within this solo was a vital part of capturing the style of Guthrie's playing. If you analyse any of his solos, the majority of which I feel are improvised, you will find a masterful control over motivic development. It is essential that you are able to identify these recurring motifs so that you can start implimenting them into your own playing and composing for that matter.
Bars 4 through to 6 illustrate the use of motivic development perfectly. That's the beauty of it; once you have a cool motif, it lays out the land for you to develop it as much as you want allowing you to attain a real coherency throughout.
