If you're a beginner or intermediate player, taking lessons from an experienced music teacher may be the best way to ensure that you develop proper technique and learn songs correctly. A qualified teacher can help beginners understand Music theory and sight-reading and provide guidance on selecting a quality instrument. Furthermore, they can provide important feedback while playing that will help you improve quickly and accurately.
On the other hand, there are some advantages to learning without a teacher, primarily the cost savings involved in skipping private music instruction. Additionally, one of the benefits of self-teaching is developing your own unique style of play based on how you respond to various techniques and sounds.
