Final answer:
The 'things of 88 keys covered by color white and black' mentioned in the question refers to a piano, which is a musical instrument with a keyboard used to create a wide range of music by pressing keys to sound notes.
Step-by-step explanation:
The item described with 88 keys covered by white and black colors is called a piano. The piano is a musical instrument that is played by pressing the keys with the fingers which, in turn, cause hammers to strike strings inside the instrument, producing sound. It is a versatile instrument used in various music genres, from classical to jazz and pop. It can inspire a range of emotions and expressions, as the keys act much like a canvas (the white card-stock model) for the pianist, allowing them to create auditory art (akin to the painted renderings of a set design).
In the words of the provided poetic reference, the 'color is the keyboard,' which refers to the keys of the piano and 'the eyes are the hammers,' representing the mechanism inside the piano that strikes the strings. Meanwhile, 'the soul is the piano with many strings' symbolizes the depth and range of music that can be produced, and 'the artist is the hand which plays,' underlining the musician's role in bringing life to the instrument.
