Why this word is great
MUSICASTER — [Noun] A mediocre or inferior musician; a pretender to musical skill. From music (from Old French musique, from Latin mūsica, from Greek mousikē (tekhnē), "(art) of the Muses") + the pejorative suffix -aster (from Latin, indicating inferiority or incomplete resemblance). Unlike a musician, a neutral practitioner, or a virtuoso, a master of gleaming technique, the musicaster dwells in the valley between aspiration and execution. He is the earnest flautist whose every note is a breathy, uncertain sigh; the church organist whose hymns lumber from key to key with a ponderous dignity; the singer in the tavern whose vibrato cannot mask the drifted key. One pities the effort, but must flee the result—a ghost in the machine of art, a reminder that love for a thing does not confer grace upon it.
