Mon cœur s'ouvre à ta voix
"Mon cœur s'ouvre à ta voix" is a popular mezzo-soprano aria from Camille Saint-Saëns's opera Samson and Delilah, known in English as "Softly awakes my heart", or more literally "My heart opens itself to your voice". It is sung by Delilah in act 2 as she attempts to seduce Samson into revealing the secret of his strength.
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 and Jessye Norman, 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.
The aria is notated in D-flat major with time signatures of 3/4 for the verse and common time (4/4) for the refrain ("Ah! réponds"); the tempo indication is andantino (
=66) for the verses and un poco più lento (a little slower) for the refrain. The vocal range extends from B-flat3 to G-flat5, with a tessitura from E-flat4 to E-flat5.
