“Asturiana” is the second movement in Falla’s Suite Populaire Espagnole (it is the third song in the original “Seven Spanish Folksongs,” but instrumental arrangements tend to omit the original second song, “Seguidilla murciana”). Both text and music come from a folk song in the northern region of Asturias. It depicts the heartfelt lament of a grieving lover who seeks comfort from a “weeping pine tree.”
The lyrics are simple and touching—

“To see if it might console me
I drew near a green pine.
To see me weep, it wept.
And the pine, since it was green,
wept to see me weeping!”

The piano is set on a pedal, a sorrowful ostinato figure against which plaintive dissonances are littered, while the cello sings the aching, primarily stepwise melody, confined to a minor 6th range.

I find this a particularly effective movement to experiment with minimal and changing vibrato, leading most of the expression in the bow.
