How do you strengthen you vocal cords? ?

Question

I could go up higher pitches when singing and now after my friend and I went to a concert, now we both can't get to the high notes anymore. We are both first soprano and we need to get are cords back to normal or at least almost.

please anything will help

Answer 1

Practice, practice, practice!

Answer 2

use scales and different warm ups and hit higher notes by building them up

Answer 3

sounds to me like you tired your vocal cords at the concert. They may need rest. It is like getting laryngitis.

Gargle and drink sips of water often.

Answer 4

keep practicing and do warm ups daily  

Answer 5

Warm up with broken octaves daily, and don't drink milk before you sing. Sing A LOT if you don't feel like your vocal cords are getting stronger.
