Like The Beatles,, Franz Liszt stood at the pinnacle of his musical genre. Even today, their songs and overall development in their genre remain unrivaled. Both artists evoked deep psychological and emotional impacts that exceeded other artists in their genre.
Speaking solely in terms of instrumentation, both songs emphasize the use of the piano to bring out the melody of the song. "Un Sospiro," however, has a far more complex arrangement for the musician to play. "Un Sospiro" uses the hands to play both harmony and melody, but in "Hey Jude," the hands play just the harmony. The melody is picked up by the other instruments of the band. "Un Sospiro" has notes played in ascending and then descending order to create the flowing background, in legato, punctuated by notes in the third staff. Whereas, "Hey Jude" has notes that seem simple in comparison; the right hand plays simple chords, and the left hand plays single half-notes on separate scales.
In terms of musical arrangement, both songs contain an overall transcending grouping of notes. However, the notes in "Hey Jude" are simple chords each played at long intervals from one another, and the notes in "Un Sospiro" are sixteenth notes played in glissando. Both pieces begin with the piano, and the melody played in the beginning of each song is an ostinato, repeated throughout each piece.
Another similarity is that the "ending" of both pieces fade out over a long amount of time. In "Hey Jude," the beginning of the fade starts two minutes from the end of the song, and in "Un Sospiro," the final measure is played slowly in ritardando over a measure of time longer than any other measure in the piece.
