If you want to make changes to your voice in a few months, practice as often as possible. Every day or every other day. If you're working to increase your endurance for regular performances, you'll need to increase the length of those sessions. The timer will bring you back to reality, and if you have free time for it, don't be afraid to keep practicing, in a controlled manner, beyond the timer buzzer.
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. But what is more important, is it true? Should you practice every day when it comes to learning a musical instrument, in this case, your voice? Will your voice and reach improve? In addition to being a singing teacher, Tom is one of the 10 founding members of the Institute for Vocal Advancement and serves as the organization's chief financial officer and marketing director. While it may be appropriate to set a timer to meet the minimum practice time, allow a little extra time to continue if you are progressing well. It will end up being a waste of time that was supposed to be dedicated to singing and it is likely that you have not progressed.
In fact, I did just the opposite, turning off my brain and body while practicing scales or technical exercises. Vocal rest days should only be necessary if you're sick or if your voice is tense (you feel like you're losing it). For example, if you have never sung before and have just started vocal classes, doing 3 hours of practice will not benefit you: the muscles in your voice are not strong enough to hold up to 3 hours of exercise. If you are serious about your singing career and want to pursue it professionally, you should visit the Atlanta Institute of Music and Media.
This is especially true at the beginning: much of the singing has to do with the development of muscle memory for these highly specialized and coordinated tasks. But didn't we just say that there is such a thing as practicing too much? True, and an amateur singer who belts in his car a tune that is out of reach for 2 hours is significantly different from that of a trained vocalist who practices for 2 hours. I have discovered that practicing outside of my voice classes has allowed me not to have to re-learn the technique that I have already been taught simply because I can't do it all the time.
