"Mind Gardens"

There are a number of instances in "Mind Gardens" where musical or poetic characteristics match the meaning of the lyrics.

The word "high" in the phrase "On a high hill" is sung to the highest pitch in the phrase (C# D E B).

The phrase "rain pourin' down" is sung to a descending melody, with "down" sung with a descending glissando (D C# B B~A).

The sequential words "safely" and "securely" alliterate and rhyme, and these repeated sounds lend a sense of that steadfastness.

"Mind Gardens"

The phrase "the slings and arrows of outrageous fortune" in "Mind Gardens" comes from Shakespeare's Hamlet.  The title character asks himself, "Whether 'tis nobler in the mind to suffer / The slings and arrows of outrageous fortune / Or to take arms against a sea of troubles, / And by opposing end them." (III.i.65-68)

The particular alliteration of "killin' cold" (the hard K sound) gives a sense of the piercing nature of the cold.

The "walls all down" in "I tore the walls all down" is sung to a descending phrase (E D C#), so there's a musical representation of the walls' coming down.
