Sfumato is the technique of allowing tones and colors to shade gradually into one another, producing softened outlines or hazy forms. 
Does the second pert have a picture or something? what is a fresco?
Sorry, Hope this helps

Answer:
Chopin's first étude focuses on a rippling chord progression. The piece is composed in the same ternary (or A-B-A) form as most of his Op. 10 études, introducing two ideas before coming back to repeat the first.
 
        
             
        
        
        
Rolling down a backwoods Tennessee highway
One arm on the wheel
Holding my lover with the other
A sweet soft southern thrill
Worked hard all week
Got a little jingle
On a Tennessee Saturday night
Couldn't feel better
I'm together with my dixieland delight
Spend my dollar
Parked in a holler 'neath the mountain moonlight
Holdin' her up tight
Make a little lovin'
A little turtle dovin' on a Mason Dixon night
It's my life
Oh so right
My dixieland delight
Whitetail buck deer munchin' on clover
Red-tailed hawk sitting on a limb
Chubby ol' groundhog
Croakin' bullfrog
Free as a feeling in the wind
Home grown country girl
Gonna give me a whirl
On a Tennessee Saturday night
Lucky as a seven
Livin' in Heaven
With my dixieland delight
Spend my dollar
Parked in a holler 'neath the mountain moonlight
Holdin' her up tight
Make a little lovin'
A little turtle dovin' on a Mason Dixon night
It's my life
Oh so right
My dixieland delight
Spend my dollar
Parked in a holler 'neath the mountain moonlight
Holdin' her up tight
Make a little lovin'
A little turtle dovin' on a Mason Dixon night
It's my life
Oh so right
My dixieland delight
Rolling down a backwoods Tennessee highway
One arm on the wheel
