The phrase denotes musical scores arranged for piano, specifically for the Christmas carol commonly known by that name. These arrangements provide a written representation of the melody, harmony, and rhythm of the song, enabling pianists to perform it. A printed arrangement, for instance, displays the notes and chords required to recreate the piece on the instrument.
Access to written arrangements offers numerous advantages. It allows musicians of varying skill levels to learn and perform the composition. Furthermore, these arrangements often include details about dynamics, tempo, and articulation, enhancing the expressiveness of the performance. The availability of these arrangements also contributes to the song’s continued popularity and preservation across generations.
