impromptu
Without prior planning
Impromptu describes something done without preparation or planning—a spontaneous action or creation: an impromptu speech, an impromptu celebration.
As a noun, it refers to such an act, especially a piece of music composed or performed extemporaneously.
The word suggests naturalness rather than carelessness: She gave an impromptu toast that moved everyone to tears.
