Vertical Position: Vert.Pos, Stave
The vert.pos parameter determines the vertical position or height of the chord symbol
above or below the staff. In Score Styles with more than one staff, the Stave parameter
determines the staff which the vert.pos parameter refers to.
A hint: to adjust a number of chord symbols to the same height above (or below) the
staff, select them and use the Align Object Positions Vertically key command.
Rhythm Section Parts
To create typical rhythm section parts with chord symbols and Beat Slashes, select a
Score Style whose Rest parameter is set to “Slash”.
