The song is in the key of A major in cut time, with a vocal range from A3 to D5.

I don't understand the A3 to D5 reference.

Starting on the piano, the lowest note is A, so that would be A1, then A3 is the third occurrence of A from A1. D5 is the fifth occurence of D from the lowest D. It is the range of the piece, or range of the vocalist, or whatever is being referred, in terms of range, where the piano keys are often the reference point.
