帕萨卡亚（Passacaglia）是巴洛克时期晚期的一种曲式，有人说起源于意大利，也有人说起源于西班牙。有‘过道’的意思，主要是和旋进程演进出的变奏。

The passacaglia (/pæsəˈkɑːliə/; Italian: [pasːaˈkaʎːa]) is a musical form that originated in early seventeenth-century Spain and is still used today by composers. It is usually of a serious character and is often, but not always, based on a bass-ostinato and written in triple metre.
