Figure 18.5 provides a chord–scale relationship for “Confirmation” using bebop scalesonly.The selection of bebop scales is analogous to the use of modes from Figure 18.4. Inm. 2, for instance, Emin7 (≤5)–A7 uses A Mixolydian ≤13, which accommodates ^1 in itspitch structure, as does A dominant bebop ≤13, making them much better choices thantheir diatonic counterparts.Demonstrating slightly different and more advanced organization of bebop scales, the lastA section alternates between ascending and descending scalar patterns. In addition, thelast note of each measure forms a stepwise connection with the first note of the next,thereby ensuring effective voice leading between different scales. Thus the last note ofm. 26, C≥4, resolves up to D4, which begins the G dominant bebop scale on 5. Similarly,the use of B≤3 in m. 31 is a consequence of the C4 in m. 30 resolving down to the ≤7thof C7
