“Mon  Coeur s’ouvre á ta voix,” quoting Wikipedia, “..is a popular mezzo-soprano aria from Camille Saint-Saëns’s opera Samson and Delilah, known in English as “Softly awakes my heart”. It is sung by Delilah in act 2 as she attempts to seduce Samson into revealing the secret of his strength^.”

This quote from Wikipedia explains the change made to this Opera song, that convinced me to paint this music:
“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 (my emphasis).”

Here is the link to the video to a wonderful performance of this change to the music, beautifully sung by Elina Garanca.   At the end of the aria, starting  at 5:45 minutes, there is a small pause, and then she softly sings, “..Samson.., Samson, ..I love you.” That is the music of this Artwork.
