If you are new to learning to play the guitar, it is important that during your first lessons you evaluate your level of interest in the instrument. If you take a 30-minute class, you'll have between 1 and 3 hours of practice material, on average. Even then, you are likely to return the following week without having practiced properly. Voice classes pose a special problem, and that is that you can't see your own instrument.
When you play the piano, guitar, flute, violin or any other instrument, you can see your hands and the instrument working. With your voice, you can't see the inner workings of your body. And for that reason, more experimentation is required in a singing class. Are you thinking about learning guitar and becoming a guitarist? A competent tutor is vital for any successful guitar class.
It makes perfect sense to have a right person who instructs you properly on how to do things with a guitar, which you could easily go wrong without expert guidance. For a medium sized guitar that you won't need to tune as often, the Epiphone DR-100 acoustic guitar is a good choice. Instead of paying for a one-on-one class with a teacher, you'll pay a monthly subscription model to access an entire class gallery. Just as you can't master the content of a lesson in a single practice session, you can't expect to fully assimilate any lesson in a week.
If you are willing to do the extra work on your own, the price of the guitar class is justified. Most beginner guitar students begin their learning with 30-minute classes for many reasons. To find out how much to charge, you'll first need to call and see how much the standard rates for guitar lessons cost in your area. Since you won't have a guitar shop around every corner, you may have to drive half an hour to your class.
Instead, it would be better to go with an online guitar lesson where you pay a monthly fee and can learn on your own schedule. Since specialist teachers are obviously harder to find than a generic teacher who can only teach the basics, guitar lessons tend to cost more. If you want to learn quickly and avoid developing bad playing habits that are harder to break later, then weekly guitar lessons are a must. The cost of guitar lessons for beginners is cheaper if you start with a teacher who may be an expert guitarist but who only has about a year of teaching experience.
Compared to any other online guitar lesson platform, YouTube dwarfs them in terms of the size of their library. They have locations across the country and everyone can charge their own fees for guitar lessons. This means that after a one-hour guitar lesson, you may need to practice for many hours at home to receive the full benefit of that class time. Just make sure you practice each week so that in the next lesson you can learn even more, this will make each lesson much more productive.
