Sweet indeed!
She has a lovely voice, jjorge. The song is one of Iris Dement's. Here are the lyrics:
SWEET IS THE MELODY (Iris DeMent)
(c) 1993 Songs of Iris ASCAP
Sweet is the melody, so hard to come by
It's so hard to make every note bend just right
You lay down the hours and leave not one trace
but a tune for the dancing is there in it's place
The dance floor's for gliding and not jumping over ponies
where boots and gold bracelets come and meet as they should
It's for celebrating a Friday night romance
forgetting the bad stuff and just feeling good
Sweet is the melody, so hard to come by
It's so hard to make every note bend just right
You lay down the hours and leave not one trace
but a tune for the dancing is there in it's place
An arm's just an arm 'til it's wrapped 'round a shoulder
looped side by side they go stepping out together
A note's just a note 'til you wake from your slumber
and dare to discover the new melody
Sweet is the melody, so hard to come by
It's so hard to make every note bend just right
You lay down the hours and leave not one trace
but a tune for the dancing is there in it's place
