"Dear Theodosia," which is far more at ease and low-key than "Yorktown," opens with Burr singing to his newborn daughter, the titular Theodosia. Hamilton joins him, singing of his own son Philip. Both men express their gratitude, joy, and pride caused by their children, and sing of their happiness that their progeny will "come of age with [their] young nation."
This song has many different purposes and layers within the context of the show. The most obvious is that of the fatherhood of our two leads; they are taking on a new responsibility in being parents, and both men eagerly anticipate the future. Its place in the show following "Yorktown" brings another meaning to their fatherhood, however, which can be seen in the line quoted above- not only have Hamilton and Burr both fathered children, but they have also led to the recent freedom- a metaphorical "birth" of sorts- of America. Not only are they raising literal children, but they're also bringing to life a new country, which will also "come of age" under the guidance of men like Alexander and Aaron.
This brings to light another layer of the song; Hamilton and Burr's relationship. Throughout the show, Hamilton and Burr undergo various stages of being friends to being enemies, and on the "Hamilton-Burr Frenemy Timeline," this song falls near the middle, but still decidedly on the Friend side. It is after moments such as "Right Hand Man" and "Wait For It," both numbers where Burr airs grievances he has with Hamilton, but it's before the two have their true falling out, which occur more in the vicinity of "We Know" and "The Election of 1800." This song, more than any other, highlights the similarities between the men and their personalities. The choruses and bridge are sung in unison, both of them expressing the same emotion and feeling toward their children. This is contrasted by Hamilton and Burr's second duet, "Your Obedient Servant," which occurs at a similar place in Act II and is at the height of their enemy-ness and division.
Another, and slightly less obvious layer of "Dear Theodosia" is in the music. As it is a musical, Hamilton relies largely (in fact, almost entirely) on musical numbers to tell the story, so it seems natural that the music would reflect the tone and mood of the show and its characters. And this rings true anywhere you look; songs like "My Shot," "Right Hand Man," and "Yorktown" are punchy and forceful, emphasizing the strong emotions and wartime experiences of our characters, while numbers such as "That Would Be Enough," "Take a Break," and "Best of Wives and Best of Women" are tender and heartfelt. "Dear Theodosia" begins with simple piano backing, but builds to add subtle guitar and rich strings. These instruments playing their sweet, almost lullaby-esque melodies, perfectly capture Hamilton and Burr's innocent joy and swelling pride.
And on top of all of that, it's just a great song. Seriously, give it another listen. A very underrated song from the soundtrack.
