Question

what is there between b and c in scale. music

Answer 1

between any given two notes there are infinite tones that can be put in. But we look on the half way ones. So on a keyboard or a piano there's nothing between B and C. But while singing we can produce many sounds between them. This is called a Half Step

Answer 2

A standard 7 note western scale has every pitch (A,B,C,D,E,F,G) represented.
