sometimes sing wrong lyrics
It's called practice. Also retaking the recording
i cant edit the description ; so , i am writing here ; i tried to do the vocal range test ;but couldnt find my range
can any1 tell me whts my vocal range?
How are we supposed to tell your vocal range?
If you couldn't figure out your vocal range using one video, try another. Though really it isn't that hard. I honestly don't know how you couldn't figure your range out if you followed such a video...
The video should have notes in an ascending scale with the corresponding name on the screen (For example A5 or a'') to figure out the highest note, and a descending scale with the corresponding name on the screen to figure out the lowest note.
Just sing along until you can't sing along comfortably (and accurately) anymore, and note down the note on the screen. Simple...
idk if this will help you or not but why dont you try to sing along to the off vocal of the song to know your vocal range. try different songs to help you. if the other utaite sing with on a high range and low range then try that to do that. it worked for me but idk if itd work for you. and i highly recommend that you do not follow someone's else vocal range/'sing like them. it will never work that way. you gotta sing with your own range to get the best results.
and for your pronunciation, it is all about practise. i had the same problem as well but youll be surprised over time by how well you can sing like a japanese person. also, it will help if youre learning japanese as you will know how to pronounce. listening to an utaite singing while looking at the romaji lyrics will help too
