Answer 2

That way to accommodate the natural shape of the handwhen it is held horizontally ... the position of playing ... the pitches of sound, as used in the West, is divided into 12 semi-tones and in order to play properly, since the human hand is not that big and since the keys need to be a certain width to give ease of playing, they divised a system with some flat ( the white ones )and some lifted key beds (the black ones)

One of the basic requirements was to be able to play the standard harmonic intervals ... third, fifth, and octave ...The octave is the largest, and had to be reachable by one hand ... If one cannot easily reach an octave, it is a little difficult to play the instrument .... and if one can reach a 10th ... which is an octave and a third ... it is rather nice for Romantic music, say ... OK? I hope it is helpful to you .
