# Merging

In the standard copy-paste mode all note's properties are copied. Sometimes that's not what you want. Merging lets you selectively apply only one property of the copied notes onto the selected notes:

* tones,
* synchro (relative positions and durations of notes) or
* lyrics.

Contrary to standard copy-paste mode, merging does not remove or add any notes. It only updates desired properties of the selected notes.

## Pasting only tones

Let's imagine that you have already mapped one verse and one chorus of the song. You have prepared notes for the next line (either manually or e.g. by using [note tapping](/karedi/next-level/note-tapping.md)). You finetuned them e.g. by using [auxiliary note](/karedi/user-interface/playback/auxiliary-note.md) method.

At this point you realise that this line sounds similar to some earlier line so you want to copy the pitches from that line. However, it's not exactly the same line so you don't want to break the synchronization that you have already prepared.

That's where pasting only tones can be helpful.

Select the notes with tones that you want to copy and copy them as usual (*ctrl + c* or menu *Edit* -> *Copy*)

Now go back to your line, select all notes:

And use `ctrl + e` shortcut (or go to menu Edit -> Merge -> Paste Tones):

As you can see only the tones were applied, no other property of the copied notes was used.

## Pasting only synchronization

In a similar way you can paste only the synchronization. Let's undo the last step:

<figure><img src="/files/7O1qvCjreh4FmbHmTaCY" alt=""><figcaption><p>Target notes ready for merge</p></figcaption></figure>

Let's use `shift + e` or menu *Edit* -> *Merge* -> *Paste Synchro* option instead:

<figure><img src="/files/CYRMF90MTjVwtim2FgOr" alt=""><figcaption><p>Only synchro pasted</p></figcaption></figure>

As you can see this time only the relative positions and durations of notes were applied, nothing else.

## Pasting only lyrics

In a very similar way you can paste only the lyrics. Let's undo the last step once again and use shortcut `alt + E` or menu *Edit -> Merge -> Paste Lyrics* option.

As you can see, only the lyrics were applied.
