### Long, Broken (De-)Crescendo Text

Have you ever wondered how to create a dynamic marking like this:

I know I have, and as I was looking through the Chopin score above, I noticed this marking again, and having never tried to do it in LilyPond, I thought I'd figure it out.

In the LilyPond Notation Reference, under the Dynamics Section there's a subsection called "Changing text and spanner styles for text dynamics". In the example, it shows how you can customize the crescendo markings to be text instead of a hairpin and use your own markup text.

```\relative c'' {
\set crescendoText = \markup { \italic { cresc. poco } }
\set crescendoSpanner = #'text
\override DynamicTextSpanner.style = #'dotted-line
a2\< a
a2 a
a2 a
a2 a\mf
}```

We can extend this further by using successive "\<" marks, which allows us to have as many bits of text as I want in the chain, except for the last one. To end the chain, it must end on a stand-alone dynamic. This can be created with:
```do = \markup { \normal-text \italic do }
do = #(make-dynamic-script do)```
or these operations can be combined:
```do = #(make-dynamic-script (markup #:normal-text #:italic "do"))
```

Now, to create the broken-up crescendo (I'll leave the default dashed-line), we can do something like this:
```\relative c'' {
\set crescendoSpanner = #'text
\set crescendoText = \markup \italic "cre"
a2\< a
\set crescendoText = \markup \italic "scen"
a2 a\<
a2 a
a2 a\do
}```
So, all we need to do is put `\set crescendoText = \markup \italic "some text"` before the note or chord we want to attach it to and `\<` after it like we would normally do.
