soprano?

hi! whenever I hear singing techniques on a video I hear soprano or alto but I don't know what that is? can you please explain to me what alto or soprano is?

Hi, Claudia! Those are different voice types or ranges. Start by reading this article I wrote on finding your range + voice type: https://www.30daysinger.com/blog/finding-your-vocal-range.

You can also use the "find my range" tool on this site: http://www.myvocalrange.com/yourvocalrange.php and check that you're singing in tune using https://tuner.ninja/. 

SingSharp (for iOS and Android) also has a range finder function with a chromatic tuner built in: https://www.singsharpapp.com/.

ok, thank you so much!

Sure thing!
