Escala's Clubbed to Death seems to be a passacaglia. It has a repetitive line throughout, over which counterpoint is added. In fact, it sounds similar to Biber's Harmonia artificiosa-ariosa: Partita No. 5 in G Minor: V. Passacaglia.
Maybe you should reword as "is C2D best categorized as a passacaglia or some other form" to get more thoughtful responses.– Carl WitthoftFeb 2, 2017 at 12:55
1You might want to give Rob Dougan a bit of credit for C2D, though as others have mentioned he did have some help from Elgar. The "original" 1995 version is on youtube– Bob says reinstate MonicaFeb 3, 2017 at 1:16
@Bob Dougan's piece is very good. Re-use doesn't mean uncreative. Bach reused Vivaldi.– GeremiaFeb 3, 2017 at 1:55
Wow, nice find!
"Clubbed to Death" actually begins with the opening to Elgar's Enigma Variations, at which point Escala takes a part of that opening bassline and uses it to construct the form.
The definitions for "passacaglia" and "chaconne" are really a little bit vague, but there are some typical aspects of each. The passacaglia, for instance, is often in 3 (like the Biber example you showed).
But both the passacaglia and chaconne are examples of what we call a "ground bass," so I think it would be safer to just call it that.
Yes, it begins with Elgar's Enigma Variations, but the "ground bass" line is very similar to Biber's passacaglia.– GeremiaFeb 2, 2017 at 20:32
