The Salvation Army ad campaign using Hayley's Quanta Qualia had me interested in the song and the composer, Patrick Hawes. I thought I'd share what it says about the song on his website: patrickhawes.com/music
The words express a heartfelt longing for the joys of heaven - a happiness to be shared in a future moment of meeting. The ecstasy of this moment is certainly underlined by the soprano solo, with the repetition of key words 'mane', 'gaudia' and 'conventus' deepening the intensity of the yearning for bliss.
On Wikipedia, it says his brother Andrew Thomas, is a poet, and according to the CD jacket, he is the writer of the lyrics of Quanta Qualia.
The song is on his debut album, Blue in Blue, which, according to his website, made CD of the week on Classic FM in 2004, and it was nominated for a Classical Brit award. It was also voted by Classic FM listeners as the fastest ever and highest new entry into the station’s Hall of Fame. I'm guessing this is how Hayley discovered the song herself, since she did attend the CB awards in 2004. She may have bought the album, or perhaps she heard it on Classic FM radio.
Quanta Qualia was the first song I listened to on the plane on the way to Madison, flying above the clouds. Very fitting, because it's such a peaceful, ethereal song. Sarah Brightman's Glosoli was also very nice to hear above the clouds.
I was looking at all of the credits from Hayley's albums a while back, and I believe Patrick Hawes may have been involved with her recording somehow. I forgot exactly what it said, though. I think she thanked him in the credits. It wasn't merely that his name was shown as the composer of the music.
