Franz Liszt’s “Un Sospiro” (A Sigh) is the third of his Trois études de concert, composed around 1848. This ethereal piece perfectly captures its title – it truly sounds like a musical sigh, with its flowing melody that seems to float above cascading arpeggios.   

What makes Un Sospiro so captivating (and challenging) is Liszt’s brilliant writing. The melody often appears in the middle register while both hands create a shimmering accompaniment around it. This requires incredible voicing control – bringing out that singing line while keeping everything else as delicate background texture.

The piece is essentially written in three layers: the main melody, inner voice harmonies, and the continuous arpeggiated accompaniment. Managing all three simultaneously while maintaining the piece’s dreamy, weightless character is what separates good pianists from great ones.

Liszt marked the score “Allegro affettuoso” – fast but with feeling. The challenge isn’t just technical; it’s creating that sense of longing and beauty that the title suggests. Every note must breathe and sing.
