The instrument described is a clavichord.
Although not very popular nowadays, it was important between the 15th and the 19th century. In popular music, variations of it can be found in songs by artists such as Stevie Wonder and Bjork, but they mostly used the electric version of the instrument.

I like it a lot! You should do something with the letters to make them stand out more!
