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 8va─────┘: Play one octave below written pitch

8va alta/bassa lines are particularly common in piano scores, though they are sometimes used in other instrumental music.¹ 15ma alta (2 octaves above) and 15ma bassa (2 octaves below) are also occasionally used.

MuseScore automatically adjusts playback of the score under the ottava to the correct pitch.
