Hello ! I’m not a professional but i have a school perfomance and i’d like to change and arrange a song for it 
. So i hope someone will tell how to add a :intro to the song. i’m sorry but i really need some help ! 
THANK YOU !!! 
You’ll need to give a bit more information.
Which version of Audacity are you using and which version of Windows? (see pink box above)
What exactly are you wanting to do? Do you have a recording of the song and a recording with an intro that you want to add to the start of the song? We can’t see what you are doing so you need to describe in detail.
