A Missa Laetare (literally “Joyful Mass”) is a specific liturgical variant that celebrates the (25 March) and, more broadly, any Mass that wishes to convey a spirit of joyful anticipation. While the term is occasionally used as a subtitle for a particular mass setting (e.g., Missa Laetare by Giovanni Pierluigi da Palestrina, or the “Missa Laetare” attributed to a 17th‑century French composer), it can also describe a stylistic intention: a bright, major‑key, celebratory character throughout the Ordinary.
