Very often in jazz composition you see sequences where there are two chords to each measure. If the tune is particularly fast this will allow a maximum of only 4 notes per chord to solo with. It will be helpful for you to learn a string of 2, 5 resolutions for these situations. If you look at standards like "Joy Spring", "I Got Rhythm" "How High The Moon" and many others, you will notice this harmonic movement. You will see it mostly as a turnaround for the last four bars of the song to take the tune back to the top of the sequence. It is also a very good substitution for a 2, 5, 1 progression where there is only one chord per measure:

The following examples show some very typical be-bop phrases for this back-cycling progression. They are all b9 resolutions with a diminished line on each of the two dominant chords. Have fun with them...
