We are currently rehearsing the Cantique de Jean Racine, by Gabriel Fauré. The second verse of this work contains the following lyrics:
There is debate among choristers as to whether or not there should be any liaison in the fourth line between conduit and à.
My understanding is that this type of liaison (verb + preposition) falls into the optional category and would be pronounced only in very high register French, such as poetry. The *Cantique de Jean Racine *is a French version of a Latin hymn. Would this be considered sufficiently high register to require liaison between conduit and à? Would it depend on whether the work was being sung in a religious or a secular context?
