First, buy any other bass guitar accessories or necessities, as I outlined earlier in the post Other Things You’ll Need to Play Bass.
Next, figure out what method you want to use to learn bass, for example, reading awesome posts on this blog, watching bass videos on youtube, buying a lesson book, or looking up bassists in your area that give 1-on-1 lessons.
Set aside a daily practice time, and stick to it. I talk about the importance of this technique in this post, and it is something that has helped me tremendously over the years. You will start to see results immediately.
After practicing on your own, it’s time to take your talent into the real world and onto the stage. Some easier places to start playing are in a church band, in a cover/tribute band, just jamming with another musician friend, or even starting your own band.
Continue to practice and grow as a musician, and push the boundaries. After a while you might want to consider giving lessons to other beginner bass players, there are two huge advantages of this: Teaching something is the best way to learn it, and you can always use a little bit of cash on the side.
Hopefully this post got you inspired to become a bass rockstar. Well, it doesn’t happen overnight… so go practice!
