(btw thanks to thal, I've been learning from the sheet music he shared here)
Some background:
Mozart's famous aria in a piano transcription by Liszt rival Sigismond Thalberg (1812-1871). This transcription is part of a collection entitled "LArt du Chant appliqué au Piano" (the art of song applied to the piano). This collection contains 25 transcriptions of vocal works by various composers, the majority from the opera genre.
Thalberg's L'art du chant stands apart as one of the earliest examples of piano pedagogy which directed the performer's attention toward tone production rather than virtuosic technique. Thalberg's twenty-five transcriptions, in comparison to his intricate and brilliant fantasies, present a deceptive simplicity while actually making sometimes even greater technical demands. The music eschews those virtuosic elaborations that can divert and fascinate the listener, and leaves the pianist's abilities and control more exposed.
Accompaniments to the melodies may be thickened or modified for reasons of sonority, but nothing extraneous or unnecessary is added. Thalberg does not place the melodic burden on one hand only. To an even greater degree than in his fantasies, the single melodies or different voices are distributed throughout the keyboard so that both hands must form, for all practical purposes, one seamless mechanism.
