The standard staff has seven lines, three solid lines followed by a dashed middle line and then three more solid lines.  If the dashed line were a ledger line, the staff would be the same as in Notation Godjevatz.  The top and bottom lines of the standard staff represent C.  The dashed line represents F#.   Traditional rhythmic notation is used. In the image above two standard staves have been stacked to show a span of two octaves.
