Also known as the 'Bells of Rome', this work is a meditative piano transcription reflecting Liszt's late-life religious devotion. Its distinction lies in the sonorous, bell-like chordal textures that require precise voicing.
Achieving a balanced, resonant sound in the chords without overwhelming the melodic line is the central difficulty.
