跳进Passacaglia的兔子洞(1)——什么是 Passacaglia?
前些天在广播里听到了交响乐版的 Bach 的Passacaglia and Fugue in C minor,于是略微跳进了兔子洞🤣了解了一下Passacaglia这个形制,Bach的这一首Passacaglia以及管风琴的一些知识~
先是了解了一下 Passacaglia 这个形制。Passacaglia 是17世纪在西班牙起源的,这个词本身的意思大约就是 cross(passa) caglia(street)。最大的特点是有一个bass-ostinato,然后在这个基础上写很多旋律variation。一般 Passacaglia 都是三拍子的,而且有一种比较严肃的感觉。这个形制和 Chaconne 非常类似,后面也会被音乐家混合使用。
除了巴赫的这首著名的 Passacaglia and Fugue in C minor 之外,其他比较有名的 Passacaglia 还有 Handel 的 Harpsichord Suite No. VII in G minor (HWV 432)最后一个乐章, Purcell 的歌剧Dido and Aeneas 中的 Dido’s Lament,Mendelssohn 也写过一首管风琴的 Passacaglia in C minor (不愧是巴赫复兴鼻祖?😂),还有肖斯塔科维奇的 Lady Macbeth of Mtsensk Act 2 的 interlude (也有一个管风琴版本)。
扯了这么多,还是先分享一下拉我进兔子洞的罪魁祸首吧,由Leopold Stokowski改编的交响乐版 Bach: Passacaglia And Fugue In C Minor, BWV 582~
