Here, translated into English, is a teaser/soundbite from
Hector Berlioz on Richard Wagner.

Quote, on the Wedding Processional from Lohengrin:
The march introduces the chorus in duple time ("Freulich geführt ziehet dahin"), which (coming at this point) causes dismay, because it is so feeble, not to say childish, in style. The effect it produced on the audience at the Salle Ventadour was rendered all the worse by the fact that the opening measures brought to mind a wretched number in Boïeldieu's Deux Nuits, "La belle nuit, la belle fête," which has been making the rounds in the vaudeville theatres and is familiar to everyone in Paris.
