Mon cœur s'ouvre à ta voix
In the opera, Delilah is responding to Samson's words "Dalila! Dalila! Je t'aime!" (Delilah! Delilah! I love you!) which he repeats between the first and second verses of her aria. These interjections are omitted in recital performances or sometimes sung to the changed words "Samson! Samson! Je t'aime!". Samson's part in the final 22 bars of the stage aria where he joins Delilah in a duet is also omitted in a recital, although some performers, notably Marilyn Horne, have sung Samson's final words – changed as above, rising to a high B-flat. A performance takes between 5 1/2 and 6 1/2 minutes.
