Transposition is the act of raising or lowering the pitch of a selection of notes by the same interval.
In MuseScore, you can transpose your music using keyboard shortcuts, or via the Transpose dialog.
To transpose with keyboard shortcuts, first select a range of notes (See Selecting elements). Then use one of the following options, depending on how you need to transpose your music:
Press ↑ or ↓ to move the selection up/down in semitone steps
Press Alt+Shift+↑/↓ to move the selection up/down in scale degrees (Mac: ⌥+Shift+↑/↓).
Press Ctrl+↑/↓ to move the selection up/down in octave steps (Mac: ⌘+↑/↓).
The Transpose dialog gives you more control over transposition, with options to transpose to selected keys or by specific intervals.
First select a range of notes you wish to transpose. (See Selecting elements). If no selection is made, the whole score is automatically selected for transposition.
Then open the dialog by selecting Tools → Transpose...
When this is selected, you can choose to transpose to a specific key, or by specified interval.
To transpose selected notes up or down in semitone increments:
Select this to transpose the selection by a specified interval without changing the existing key signature(s). Note: the intervallic relationships between pitches in your selection will change as a result!
Transposing instruments (such as the clarinet, French horn, trumpet etc.) are notated at a different pitch (and key signature) to how they sound. The notated pitch is called the written pitch, while the actual pitch is called concert or sounding pitch.
By default the program is displayed with all the staves at written pitch. However, if you wish to view the score at concert pitch just check the "Concert pitch" box (to the left of the tuning fork icon) in the status bar.
When you set up a score in the New Score, or Add or remove instruments dialogs, transposed key signatures are automatically applied to any transposing instruments. However if for any reason you need to set up the staff transposition manually, this is how to do it.
The correct transposed key signature will now appear on the staff.
The enharmonic spelling of the transposed key signature, whether in sharps or flats, is set in Staff/Part properties (see Setting the interval of transposition ).
To change the enharmonic spelling of pitches in the score, see Change spelling.
