Screaming = Bad (usually)

Why Screaming Hurts

First of all, if you scream too much, your voice will literally hurt. Singing is like an intensified version of talking, in which your voice box vibrates down in your throat. You can feel it vibrate if you touch your neck, and talk. See? So screaming really over works your voice box, and that’s part of the reason why people lose their voice, it’s because they over work it, and then it stops working altogether until it heals.

Why Screaming Hurts Listeners

Especially for beginners, screaming is very difficult to do (the right way), and so it usually sounds awful. And screaming too much can really wreck a good performance, if the singer is just going crazy with out of tune screams. You need to learn to control your screams, or at least tune them to the song. Short like screams are fine, as they add energy to the performance, but long, drawn out screams at the top of your lungs will defiantly sound worse then you think it will.

Steps to Take:

Record little bits of your songs on garageband, or on a handheld recorder
Practice screaming to the song
Listen to it! And adjust your scream to sound better with the song

Luckily once you get a hang of screaming, it will be much easier, it’s just in the beginner stages that it’s much harder. There are even singers who base their whole vocal style off a lot of screaming. These people must have strong voices, because most people will lose their voice after one or two days of vigorous screaming, so I wouldn’t recommend trying this.

In summary:

Screaming doesn’t sound good if it isn’t tuned
Short screams sound much better
Practice your screaming
Good screaming can be attained, it just takes practice
