Conditional sidebars according to category and children

Hello

For single post I want to create a conditional to bring in certain sidebars according to the categroy that the post is in.

For example I would like to call in the sidebar_music.php when the post is in either music or a subcategory (child) of music. Music is a section or category of my site and is assigned cat ID 5

Thus the music sidebar would appear in both these cases
https://mysite.com/music/article
https://mysite.com/music/concerts/article

I assume the code would look something like this. I am a novice with PHP so I don’t know the correct syntax but the perintent functions and logic are basically here. My main problem is I do not know how to define the category and ALSO the children of that category within this conditional.

<?php

if(is_category(‘5&&child_of=5’))

include (‘music_sidebar.php’);

elseif (is_category(9&&child_of=9))

include (‘tv_sidebar.php’);

elseif (is_category(8&&child_of=8))

include (‘dining_sidebar.php’);

?>
