How long does it take to practice singing or singing every day?

This should be mastered according to your own ability. You can't practice for too long when you are a beginner, and then add time bit by bit. Usually practice for more than an hour, you'd better have a rest and drink some water to adjust, otherwise your voice will be too much. The effect of singing in the morning should be the best. Don't practice songs for more than four hours every day, and rest your voice. Don't play high notes all the time, start with the low scale and rise a little. Don't eat too much polysaccharide, drink plenty of water to protect your throat. Don't practice your voice for a long time, you need to have a rest. When you have a sore throat, you'd better not play high notes if you want to shorten your vocal practice time. If you really want to practice, I suggest singing softly. Pay attention to keep warm and try not to catch a cold, otherwise it will block the nasal cavity and affect the effect of practicing vocal music. Buying some lozenges will also help. If you practice pop songs, you can practice more. Of course, if you feel dry or sore throat, you should stop immediately. Don't be brave. Even if you have leisure, you can't continue to practice, otherwise your voice will be hoarse and it will be difficult to recover.
