In Kingdom Hearts II, "Missing You" is heard during "A Letter to a Boy," "The Blood in Will," "The Easy Life," "Wind's Tidings," "Timon and Pumbaa," "Hakuna Matata," "Axel Closes in on Kairi," and "Stolen Rose."
"Missing You" is approximately forty-six seconds in length and plays at a steady 64 beats per minute in a slow 4/4 meter. It is written in the key of e minor, and makes frequent use of leading tone suspensions as with many Kingdom Hearts pieces. While piano is the featured instrument, strings can be heard in the first phrase. The simple chordal melody is supported by ostinato arpeggio eighth notes in the left hand.
