Editing Musical notation (section)

===Piano-roll-based notations===
Some chromatic systems have been created taking advantage of the layout of black and white keys of the standard piano keyboard. The "staff" is most widely referred to as "[[Piano roll#In digital audio workstations|piano roll]]", created by extending the black and white piano keys.

====Klavar notation====
{{Main|Klavarskribo}}
{{lang|eo|Klavarskribo}} (sometimes shortened to '''klavar''') is a music notation system that was introduced in 1931 by the [[Netherlands|Dutchman]] Cornelis Pot. The name means "keyboard writing" in [[Esperanto]]. It differs from conventional music notation in a number of ways and is intended to be easily readable. Many klavar readers are from the Netherlands.
