Ebeneeeeeezer Scrooooooooge. All those hard consonants and vowels together are the perfect name for Dicken's protagonist of A Christmas Carol.
The first observation is that it is the perfect name to be uttered by ghosts with their ethereal and echoing voices. Each of the three speaking ghosts says the name with a similar drawn out manner, but with a change in inflection that relates to the meaning of that particular spectre's visit.
Marley, of course, is a fearful spectacle of money boxes and ledgers and chains. When Marley speaks the name of Scrooooooooge, it is accompanies by a wail and a chill. Marley focuses on the hard consonants of Ebenezzzzzer Scccrrooggge, adding a harshness to the reality of Scrooge's current spiritual condition.
The Ghost of Christmas Past has a softer inflection, more akin to the nature of nostalgia's worn edges. When this ghost speaks the name of Ebenezer Scrooge, the reader understands that the path ahead is not as dark and frightening as Marley's visit. This spectre speaks with the gentleness of a teacher who uses the vowels of the name as a caress instead of an accusation. Scrooge may not recognize it, but it is the first hint of kindness shown to him in the use of his name in many years.
The Ghost of Christmas Present brings a laughing joyfulness to the name Ebeneeeeezer Scroooge. His inflection move up the tonal scale instead of down, and again, the vowels serve to lighten the mood of the scene. Toward the end of the scene, however, the ghost begins to apply more emphasis to the consonants, especially as he describes the children, Ignorance and Want. Scrooge had to understand that HE was part of their existence, and the harsh consonants of his spoken name took him back to Marley's visit and the dread that accompanied it.
The final spectral visitor, the Ghost of Christmas Yet to Come, is silent, but by this time, Ebenzer Scrooge understands that the lesson he is about to learn has everything to do with his own future. When the ghost shows Scrooge the gravestone, the letters stand out in the solid stone of concrete in a permanent expression of miserliness and misery.
Interestingly, the name "Ebenezer" means "the stone of help." In the Bible it is the name of a "stone of rembembrance" set up by the prophet Samuel. Samuel had been making a sacrifice to the Lord when the Philistine army attacked the Israelists. This sneak attack was not exactly in accordance with the Code of Chilvary, and the Lord gave the Israelites the ability to out run and defeat the Philistines, even though they were greatly outnumbered. The Bible relates the response of the prophet:
Then Samuel took a stone and set it up between Mizpah and Shen. He named it Ebenezer, saying, "Thus far the LORD has helped us." (1 Samuel 7:12, NIV)
By choosing the name Ebenezer, Dickens sets up a foreshadowing of Scrooge's future. The ghosts came as other-worldly emissaries in order to show Scrooge that he could still turn from his ways and make his penance. He, like the Israelites, could chase down his enemy (his own miserly nature)and overcome it. The moment of his epiphany became his own stone of remembrance. He says as much at the end when he dances and stumbles around his home touching things and attaching memories of the spectres to them so that he would never forget the events or importance of the events.
Or maybe Dickens just thought the name sounded cool when spoken by spectres....
