The Transcendental Études (French: Études d'exécution transcendante), S.139, are a set of twelve compositions for piano by Franz Liszt. They were published in 1852 as a revision of an 1837 set (which had not borne the title "d'exécution transcendante"), which in turn were – for the most part – an elaboration of a set of studies written in 1826.
Transcendental Étude No. 1 in C major, "Preludio" is the first of twelve Transcendental Études by Franz Liszt. It is the shortest étude of the set, lasting approximately a minute. The piece begins with low octave Cs, followed by a downward run made up of an arpeggiated C7 chord. A furious set of impetuous notes then climb chromatically, and it returns to the octaved Cs and the downward run. The furious set of notes climbs even higher and a set of loud chords blare in fff. The left hand then plays loud, low pitched trills in succession. After that, the right hand plays some intense arpeggiated figures, closing with a final chord. This étude is one of the less difficult to play along with Transcendental Étude No. 3 (Paysage).
