Ihe sheet music excerpt below is the first few bars of the tune “On Green Dolphin Street”. Take a look at the last two measures before the final C chord (measures 9 and 10). The chord symbols say Dm7 and G7, or ii7-V7. Usually, in fake or real books, these are the chords you play (not what I put in the bass clef). In an actual playing situation, you certainly wouldn’t want to play the bridge the way I’ve suggested each time–it would get old very fast. Like spoken language, the more ways you can say the same thing, the more fluent you are with your vocabulary. In many cases, the dm7/G7 is just a subdivision of on what could be G7 for 2 measures. Here, those 2 measures are functioning as Dominant harmony. For a moment, leave the bass line out of the analysis, as it is just walking up from D to G. The inner 3 voices in the bass clef, have a similar pattern as the whole-note walk down in the post Alternative Voicing for Piano (1). The difference is that here they are moving up in minor thirds every other beat. They are, again, simple major triads in 2nd inversion, falling on the downbeats. On the offbeats, the chords follow the same pattern again as in the post Alternative Voicing for Piano (1). If you care to analyze deeper, beat 3 of measure 9 is an implied G7#9. Beat 1 of measure 10 is a G7b9+11 (aka Db/G7). Beat 3, measure 10 is a G13b9 (easy to do on a guitar, as well)..
The song is usually played with latin beat through the A section, and swing for the bridge (at the Dm7). Also, the bridge continues with a parallel section in the key of Eb (not shown).
