Shir haShirim Zutta is very different in nature from Shir haShirim Rabbah. Zutta is a homiletic commentary on the whole text, and does not contain any proems; some verses are treated at length, while others are dismissed very briefly, sometimes only one word being discussed.
Shir haShirim Zutta is distinctly dissimilar in character from Shir haShirim Rabbah. Zutta serves as an exegesis on the entire text, lacking introductory poems; some verses are exhaustively analyzed, while others are cursorily addressed, occasionally only a single word being elaborated.
