Mom & Dad

Mom & Dad, top of page 87 from the Songbook. The first two bars are the two instrumental bars, followed by the return of theme 1.
Nominally this example is in E Dorian. It begins like that and the text of theme one ends here with "lay" (not shown above), coinciding with the first chord of the instrumental bars, that follow upon it. It thus begins and ends in E Dorian, but in between it's more multi-scale oriented.
