Learning to play the guitar can be a daunting task, especially if you're starting from scratch. With so many resources available online, it can be difficult to know where to start. While it's possible to learn the basics from YouTube tutorials and other free resources, taking a few suitable lessons can help you progress much faster. A teacher can help you identify and correct any mistakes you may be making in your technique.
Online lessons are a step up from self-teaching, but they may not be as effective as having someone examine your playing in person. At the beginning, there are plenty of free resources available, such as Marty Schwartz and Justin Guitars. These can help you get off to a good start and give you enough time to decide if you need more complicated elements and lessons. Realistically, while it's possible to pick up one or two bad habits without direct classes, no teacher can give you anything that YouTube can't when it comes to learning the basics.
Once you've gotten through the basics, online learning can be beneficial if you have a clear idea of what your learning objectives are. Otherwise, it can be overwhelming due to the sheer amount of information available. Private classes are usually preferable if you have a good teacher, but they can be expensive. If you're on a budget, buying a package of books may be cheaper than a live guitar lesson and will cover more ground.
It's important to remember that everyone who has mastered the guitar beyond a certain point has taken lessons at some point in their lives. If you're just starting out, taking classes is the best way to get off on the right foot and avoid developing any bad habits. After taking classes for a while and learning basic music theory, online lessons can help supplement your learning experience.I had a guitar for years before I took classes and learned how to hold it properly so as not to silence the strings constantly. After taking classes for a year, I was able to go much further with online lessons.
However, I don't think I would have been able to properly absorb knowledge from online resources without first learning the basics from a teacher.In conclusion, online guitar lessons can be beneficial if you have a clear idea of what your learning objectives are and have already learned the basics from an instructor. However, private classes are usually preferable if you have access to a good teacher.
