# Transposition
**Transposition** is the act of raising or lowering the pitch of a selection of notes by the same [interval](/3/appendix/glossary.md#interval). You can choose to transpose notes either [manually](#manual-transposition) or by using the [Transpose dialog](#automatic-transposition).
## Manual transposition
1. [Select](/3/basics/selecting-elements.md) the notes that you wish to transpose;
2. Use any of the following options:
* **To transpose chromatically** (i.e. one semitone at a time): Press Up or Down. Repeat as required.
* **To transpose diatonically** (i.e. one scale degree at a time): Press Alt+Shift+Up or Down. Repeat as required.
* **To transpose by an octave**: Press Ctrl+Up or Down (Mac: Cmd+Up or Down).
## Automatic transposition
MuseScore's **Transpose** dialog gives you more options for transposing notes.
**Note**: By default this dialog opens from the **Tools** menu, but you can also choose to open it using a keyboard shortcut (see [Preferences](/3/advanced-topics/preferences.md#shortcuts)).
### Transpose Chromatically
#### To Key
To transpose notes up or down to the desired key:
1. [Select](/3/basics/selecting-elements.md) the notes you want to transpose; no selection equals "select all.".
2. From the menu bar, choose **Tools -> Transpose…**.
3. Tick "Transpose Chromatically" and "To key".
4. Tick/untick "Transpose key signature" and "Transpose chord symbols" if required
5. Tick one of "Closest", "Up" or "Down" and select a destination key signature from the drop-down menu.
6. Click OK.
#### By Interval
To transpose selected notes up or down in semitone increments:
1. [Select](/3/basics/selecting-elements.md) the notes you want to transpose; no selection equals "select all".
2. From the menu bar, choose **Tools -> Transpose…**.
3. Tick "Transpose Chromatically" and "By Interval".
4. Tick/untick "Transpose key signature" and "Transpose chord symbols" if required.
5. Tick "Up" or "Down"; and select a transposition interval from the drop-down menu.
6. Click OK.
### Transpose Diatonically
To transpose selected notes up or down by a diatonic interval:
1. [Select](/3/basics/selecting-elements.md) the notes you want to transpose; no selection equals "select all".
2. From the menu bar, choose **Tools -> Transpose…**.
3. Tick "Transpose Diatonically".
4. Tick/untick "Keep degree alteration" and "Transpose chord symbols" if required.
5. Tick "Up" or "Down;" and select a transposition interval from the drop-down menu.
6. Click OK.
### Options
Two options are available for both Chromatic and Diatonic transposition mode in the options area:
* **Transpose chord symbols**, if required.
* And the choice of **Use Double ♯ and ♭** or **Single ♯ and ♭ Only**
## Transposing instruments
**Transposing instruments**, such as the B-flat trumpet or E-flat alto sax, sound lower, or higher than their written pitch. MuseScore has a number of features to facilitate the scoring of these instruments.
### Concert pitch
MuseScore's default viewing mode shows the musical notation in **written pitch**, but you can choose to display the score in [concert pitch](/3/basics/concert-pitch.md) instead. In the latter mode, the musical notation of *all* instruments matches the actual pitches that you hear on playback.
* **To change the view to concert pitch**: Press the [**Concert Pitch**](/3/basics/concert-pitch.md) button to highlight it.
You should ensure that the Concert pitch button is OFF before printing the main score or any parts.
### Change staff transposition
Instrument transpositions are already set up in MuseScore. However, if you want a rare instrument or transposition that is not available in MuseScore, you may need to edit the instrument transposition manually.
1. Right-click an empty part of the instrument staff and select **Staff/Part Properties…**.
2. At the bottom of the window, select the interval of transposition, any octave shifts, and whether the interval is "Up" (sounds higher than written) or "Down" (sounds lower than written).
You can also use the **Change Instrument…** button in the Staff/Part Properties window to automatically change the transposition to that of a different standard instrument.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://handbook.musescore.org/3/notation/transposition.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
