One of the most important things for you to do is make sure that you are attending the right networking events. When you are just starting out, it can be less intimidating to go to local musician meet-ups or other much smaller networking events where you can start off slowly.
Going straight to a convention center sized networking event may be a bit overwhelming to those who are new to the industry, so really work your way up to these larger events when you get more networking experience.
The large events typically bring higher quality networks, so you want to really make sure that you have mastered your networking skills when you go to these events. You should also choose your networking events based on your specific genre, which is where you are going to find more people who are interested in your type of music. For instance as a rock musician, you may not find anyone at a rap centric event to network with.
