In general, singing while standing can burn 136 calories per hour. The more you move while singing, the more calories you burn. The heavier you are, the more calories you burn. If you play an instrument or dance while singing, you'll burn even more calories.
This is because to sing effectively, you need a lot of endurance and technique. With each note you hit, your body uses numerous muscles to participate, help you breathe, boost your voice and produce a smooth, consistent tone. Singing burns around 136 calories per hour, depending on your size and the amount of energy you use. As you sing, you use your abdominal muscles to exhale and your diaphragm to inhale, exercising your muscles to increase your metabolic rate and burn calories.
If you want to lose weight, physically active exercises, such as running, are more beneficial than singing. However, if you are persistent, singing can be considered exercise. Small studies have indicated that this type of singing may have cardiovascular benefits, but weight loss is unlikely, and one study suggested that singing could predispose singers to gaining weight. It doesn't matter if singing can help people lose weight, singing is still one of the ways people release stress.
If you want to optimize the singing effect, you have to sing an entire playlist out loud, try hard notes, play a musical instrument and dance while singing. Combining singing with dancing will definitely count as an exercise, so try to do some routines that go with your singing. Singing won't make you lose weight like running or exercising at the gym does, but singing while standing up will burn a comparable amount of calories to walking, yoga, or doing light household chores. Singing exerts a lot of energy and it's hard to sing on the field if you're not in physical shape, since you need to be able to boost your muscles.
I also agree that singing helps relieve stress even if you're the worst singer in the world, random dance parties and singing along are the easiest way to make new friends and get out of your shell, and apparently lose weight while doing it. So how many calories do you burn singing for 1 hour? The answer depends on your weight, body size, singing style and how much energy you use for your performance.
