Does Пение louder help me to sing better?

Well, Пение louder would help! Its probably harder to hit notes when your Пение softly. But i'm not saying to scream because that's ridiculous. But to be better, sing more. I had a problem similar to that when I was in 6th grade. I'm going into 9th and I've done a a few solos. I've also been in Womens Chorus for 2 years. Пение louder is better. So remember practice singing. And maybe Ты cant hit high notes because thats not your octave. Instead of Пение soprano, try Пение alto! Very few people can do both или extend that range but try Пение songs on a lower note! Its worth a try! And if that's not it, Ты may be one of those people that have a very limited range. That's probably harder to deal with. If that's the case, I can not help Ты anymore because my range is very extend it. I can do Soprano 1(pretty high) to Alto 2(pretty low). So I hope I helped Ты with your situation!

Well, depending on your volume level BEFORE Ты get louder...
if you're really really quiet then yeah.
but if you're normal volume, it doesn't help at all, just makes Ты sing off-key, trust me i know.

Well I'm not too keen on singing. But clearing your throut and by drinking plenty of water it might help. By the way the еще talking Ты do the better your voice will sound like.
Peace and love!

Definately! But don't yell, part of Пение louder and better is the confidence Ты have. If Ты aren't confident, you'll suck. Also, Ты need to breathe properly. Usually, when people breathe they inflate their lungs and their shoulders go up. When you're Пение Ты need to breathe into your diaphragm, making your belly extend. Thus your voice will be stronger, louder, better, and you'll be able to hold a note longer, Plus, the high and low notes become much easier. Also, I know Ты didn't ask about this, but if you'd like to be able to hit notes better, and widen your octave scale, find a Пианино или keyboard. Start at middle C, then just press notes and try to hit them perfectly. Go higher или lower at your leisure. You'll find major improvement!

When I sing quietly, my voice sounds hoarse. Ecspecially on high notes. This is common so don't worry about. And about the main question, yes Ты probably will sound better if Ты sing louder and are confident.

I can help Ты sing better if Ты sing louder

This is not true. If Ты understand proper dynamics that is what will make Ты sound better. Trust me

Not exactly. Practicing to song, yes, it does make the high notes easier to hit, but it can also make it sound a bit awkward, and depending on the song and your vocal type it could just make it worse. In any case, don't try to sing as if you're yelling, but if Ты are working on hitting high notes don't sing too soft either. It's all about finding the perfect balance. For instance, Ты may just not have a high voice, and Пение loud to try and hit high notes would be pointless because it would just make it louder, not better, или maybe Ты just need to develop your voice, in which case, Ты should try every thing.

no! first of all, Ты have to have a ear for music, knowing when to change on your voice patterns. listen to a song, over, and over again, until Ты get sick of it. and other melodies, that will bring out your best voice vocals
