Ossias in MuseScore: How to Add Them

An ossia is a small extra staff above a passage that shows another way to play it. In MuseScore 4 it is made with an extra staff whose empty measures are hidden: turn on “Cutaway” in Staff/Part properties and write the ossia only in the measures where it goes.

This MuseTube lesson shows how to create an ossia measure in MuseScore. Ossias are often used as performance guides: they show an alternative version of a passage or how a specific section should be played.

🎼 What Is an Ossia?

An ossia is an auxiliary measure that appears above the main staves. Its main purpose is to show an alternative way to interpret a musical passage or explain how a specific element—such as a trill or ornament—should be played. It is not always performed but serves as a reference for the performer.

🛠️ Showing and Hiding Measures in MuseScore

MuseScore allows you to hide staves or measures that contain no notes. This is useful for visually simplifying a score and focusing on relevant musical content. To activate this feature:
  • Right-click on any measure.
  • Select “Staff/Part Properties”.
  • Enable the “Cutaway” option.
  • Apply changes to hide all empty measures.
This functionality can be applied not only at the staff level but also at the measure level. You can switch between instruments or staves using the up and down arrows in the menu to apply the same settings elsewhere.

🧪 Step-by-Step: Creating an Ossia Measure

Here’s how to create an ossia measure from scratch using a flute line as an example:
  • Enter several notes in the main staff (e.g., flute).
  • From the Instruments panel (called Layout in recent versions; open it with F7), select “Add staff” for that instrument.
  • Move the new staff to the top (this will be the ossia).
  • Right-click the new staff and go to “Staff/Part Properties”.
  • Check “Small staff”.
  • Enable “Cutaway” to show only measures with notes.
  • Uncheck “Show barlines” to hide measure lines.
In this upper staff, you can write a run of sixteenth notes simulating a trill, as a visual explanation for how it should be played.

🧹 Final Visual Adjustments

To fine-tune the appearance of the ossia:
  • Remove unnecessary system braces.
  • Use the “Fixed spacer below staff” from the “Layout” section in the “Palettes” menu.
  • Adjust the spacing in the “Properties” tab until both staves are visually aligned.
These steps will ensure your ossia measure is visually integrated into the score while remaining clearly distinguishable as an interpretive guide.

📤 Exporting the Score

Once your ossia measure is finished, you can export the score as usual. The ossia will appear at the top, offering a visual explanation without interfering with the main musical flow. This technique is particularly useful for trills, ornamental runs, suggested fingerings, or other non-essential elements that enhance performance without cluttering the primary notation.
