Octave (Ottava) lines are used to indicate that a section of music is to be played one or more octaves above or below written pitch: The line may be dotted or solid. Ottavas are available in the Lines palette of the Basic and Advanced workspaces.
8─────┐or 8va─────┐: Play one octave above written pitch (Treble clef only)
8─────┘or 8vb─────┘: Play one octave below written pitch (Bass clef only)
8va/8vb lines are particularly common in piano scores, though they are sometimes used in other instrumental music.1 15ma (2 octaves above) and 15mb (2 octaves below) are also occasionally used.
(Debussy. Études, Book II, X)
