Answer 
Pianos have both white and black keys for several reasons, including musical and practical considerations:
Musical notation: The arrangement of white and black keys on a piano keyboard corresponds to the layout of notes in Western music notation. The white keys represent the natural notes (A, B, C, D, E, F, G) of the musical alphabet, while the black keys represent the sharps and flats (notes with alterations in pitch).
Scale patterns: The arrangement of white and black keys follows a repeating pattern of seven white keys and five black keys, which corresponds to the seven notes of a diatonic scale (such as the major or minor scale) with the added sharps and flats in between.
Visual and tactile differentiation: The contrasting colors of the white and black keys help pianists visually and tactilely distinguish between different notes and intervals, facilitating accurate and precise playing.
Historical evolution: The use of black keys to represent sharps and flats dates back to the early keyboard instruments, such as the harpsichord and clavichord. This layout was retained in the design of the modern piano for continuity and familiarity with existing musical conventions.
Overall, the arrangement of white and black keys on a piano keyboard serves both practical and musical purposes, helping pianists navigate the instrument and interpret musical notation effectively.
