Is 歌い踊り舞う a compound verb or something else?


I came across this line from YOASOBI's song 「アイドル」:

> 流れる汗も綺麗なアクア  
>  ルビーを隠したこの瞼  
>  **歌い踊り舞う** 私はマリア  
>  そう嘘はとびきりの愛だ

I'm having some trouble with the bolded part and I want to break it up
grammatically.  
I've tried to look up [歌い](https://jisho.org/search/%E6%AD%8C%E3%81%84),
[踊り](https://jisho.org/search/%E8%B8%8A%E3%82%8A),
[踊り舞う](https://jisho.org/search/%E8%B8%8A%E3%82%8A%E8%88%9E%E3%81%86),
[歌い踊り](https://jisho.org/search/%E6%AD%8C%E3%81%84%E8%B8%8A%E3%82%8A) and
[歌い踊り舞う](https://jisho.org/search/%E6%AD%8C%E3%81%84%E8%B8%8A%E3%82%8A%E8%88%9E%E3%81%86)
on Jisho but could find only 踊り and 舞う. This makes me think that it isn't a
single verb but some compound verb using the ます-stem of 歌う and 踊る as in:

> 歌う + 踊る + 舞う = 歌い ~~ます~~ + 踊る + 舞う = 歌い踊り ~~ます~~ + 舞う = 歌い踊り舞う

What I'd like to understand this construct, translate it and if possible find
some alternative ways to say the same thing.  
So for the first part, about understanding the grammar and the sentence, is
this the continuative form of 歌う and 踊る? And then it would translate as
"Singing and dancing while whirling\fluttering about" or just as an elaborate
way of saying "singing and dancing"?

For alternatives, how about「歌い踊る」? Because both 踊る and 舞う can mean "to dance"
or maybe use ながら to imply that both are happening at the same time「歌いながら踊る」?
Maybe it can be replaced by 「歌って踊って舞う」 or use ながら somewhere in between to
imply that both are happening at the same time?

Thanks!




歌い踊り舞う(私) is not a compound verb listed in a dictionary. It's just three verbs
connected using [中止法](https://japanese.stackexchange.com/q/9771/5010). In
other words, it's roughly the same as 歌って踊って舞う(私).

踊る and 舞う both translate to "to dance", but they refer to different types of
dancing. 踊る refers to dynamic and rhythmical ones, while 舞う refers to
relatively slow and elegant ones like in [this
video](https://youtu.be/GPIJ6aUDkio). See [this
article](http://kokugojuku.com/blog2317), too.

By the way,
[舞い踊る](https://dictionary.goo.ne.jp/word/%E8%88%9E%E8%B8%8A%E3%82%8B/) is a
lexicalized compound verb, but it's not used in this song.
