Where does middle c get its name from

Middle C, though, does get its name from its position between the bass and treble clefs that make up the typical Grand Staff.

so basically there is this thing called a grand staff and it is essentially just the treble clef and bass clef staffs put together so it would have ten lines and eight spaces not 5 and 4.  middle c got its name because it is sitting in between in treble clef it is right down the bottom but in bass clef it is right up the top.  this is the same note equivalent

soft,hard and rough for soft would be a pillow or a stuffed animal hard wood floor or a table rough paint
