Ironic (song) [SEP] Writing and composition
"Ironic" was written by Alanis Morissette and Glen Ballard, and produced by the latter for her third studio album, "Jagged Little Pill" (1995). In an interview with Christopher Walsh of "Billboard", Ballard explained how he and Morissette met, and how "Ironic" was written. He commented: "I'm telling you, within 15 minutes we were at it—just writing. 'Ironic' was the third song we wrote. Oh God, we were just having fun. I thought 'I don't know what this is—what genre it is—who knows? It's just good". According to the sheet music published at Musicnotes.com, it is a song set in the time signature of common time, composed in a moderate tempo of eighty-two beats per minute.
