For MuseScore 3 users, see Octave lines
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
8─────┘or 8vb─────┘: Play one octave below written pitch
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.
