However, beginners may practice too much and should stop if they feel vocal tension. Taking breaks throughout the day allows those who don't have vocal endurance to practice more daily. Singing students usually practice two hours or more every day. That doesn't include time spent learning to sing at first sight, dictating, playing the piano, and absorbing knowledge related to singing, such as anatomy, music theory, and music history.
If you want to make changes to your voice in a few months, practice as often as possible. I have discovered that practicing with one of the computerized music practice programs with the bass has helped me tremendously. In fact, I did just the opposite, turning off my brain and body while practicing scales or technical exercises. I do this less on my own when I am in sets that have 1-2 hour practices, since those rehearsals act as my technical training.
Constant practice will also allow your brain to quickly grasp the concepts associated with good singing. If you have specific habits that you want to change in your voice over the next 6 to 12 months, you'll have to make it happen with regular practice. If you like to explore your voice and what it can do at a slower pace because you don't have any performance aspirations, stop hitting yourself for not getting hot every day. The smaller and more frequent bits of GOAL-ORIENTED FOCUSED practice are much better than singing some songs and exercises with no idea what habits are supposed to change.
So my question to you is what is the best thing you can do between practices to make you feel fresher and ready to go back to practice? Even so, under these circumstances, the principles of conscious practice are the same even if you need more than four hours to cover everything. With this in mind, as long as you can stay focused, productive, and fully aware of what you're trying to achieve in your practice session and not just repeat passages without thinking over and over (which can create bad habits that are hard to unlearn), I think you can feel free to practice whenever you do.” like it. Taking care of your body and mind outside the practice room is crucial to helping you achieve your goals (in any discipline). It won't tell you which Harry Potter character you are, but it will guide you in the direction of some new practice methods that could help you level up in the practice room and on stage.
