However, a class at least once a week is beneficial to 99% of our students.
Voice classesare usually divided into 30-, 45- and 60-minute sessions. Normally, students benefit from more than one 60-minute class each week to work in-depth on their voice and watch a song at the same time. This gives the teacher, and you as a student, an idea of how well you are practicing and progressing.
The standard frequency of classes is one class per week. Some people want to do more right from the start and others want to do less than that. For most people, I recommend consistent weekly classes as optimal if possible for them. In my experience, people who plan to do two or more lessons a week find that they don't actually progress much faster.
It takes time for the body to develop new habits, and singing is a rather sophisticated process for the body, since many things have to align. That said, you can speed up this process by simply practicing more. The 3-year rule for me is a singer who practices 1 hour a day at least 5 days a week. If you practice two hours a day, you can speed up this process tremendously.
It all depends on how much you want it and your willingness to spend time. Just as some people learned to walk faster than others or learned to speak before, people progress differently with the voice. The ideal situation is that you find a good teacher in person and take weekly classes with him, at least until you build a good foundation for your voice. As for the time it takes to see results, it depends on a number of factors: what your goals are, where your voice is right now, and how dedicated you are to making the changes you need to make to achieve your goals.
Singing is pretty much the same: yes, you work with your voice instead of your body, but the basic way of training is the same. Playing with your voice is fascinating, but it can also be dangerous if you don't know what you're doing. Your voice is a very intimate and precious part of you, and you want to trust it to someone you really trust. The voice is one of those instruments in which simply laying the foundations is such a task that most people never get to that point.
The overall goal of any aspiring singer should be a healthy and balanced voice that lasts the rest of your life. If you are looking to go beyond the basics and learn to distort the voice, spread the voice from your chest as much as possible, etc.
