韋瓦第的十二首協奏曲 Op.4 以“La Stravaganza”的名字而聞名。
"La Stravaganza"的多次重印見證了它在 1730 年代的流行和廣泛傳播。除了倖存的版畫外，還有大量手寫資料包含七首協奏曲的替代版本。其中一些手稿來自 Johann Georg Pisendel 的音樂庫。
此版本的《La Stravaganza》不僅是第一個學術評論版，也是唯一可用的完整版本。除了羅傑版中流傳下來的 12 首協奏曲外，Bärenreiter 還提供了一部額外的協奏曲，包括全譜、鋼琴還原和由英國出版商 Walsh & Hare 發行的 1728 年印刷品中包含的部分，以及其他版本（沒有中提琴）在第 6 號協奏曲（第 1 卷）和第 11 號（第 2 卷）的手寫資料中。
