"Beautiful." 

"Beautiful" is a word that we use to describe something that is harmonious, pleasurable, or aesthetic. We call vast and dazzling landscapes "beautiful". 

We say that a moving speech was beautiful. 

Beautiful music we hear nearly everyday. 

By this post I would like to add to this list of beautiful things one source of beauty (a source of music).

 And that is a grand, powerful yet delicate, marvelous conglomeration of strings, hammers, pedals and ivory — the piano.
