Lets start from the beginning.
The first question you ask yourself, "Is playing bass guitar what I want to play?" That is the most important thing because as everyone knows when you want to get started in something it is going to be a small investment. With today's economy nobody wants to waste money on something they are not sure they should do. Playing bass guitar is not what I started doing, I started on acoustic guitar and played that for quite a few years, then started playing with a few friends and then it started to get serious and we formed a small three piece acoustic band. As the band grew, we then needed a bass guitar player so I put down the acoustic and started playing bass guitar. The point is that I had put out cash to get set up in two different things, now that is ok if that is your plan to play two different instruments.
The next thing you should think about is your musical talent and if you are ready to put the time into playing bass guitar, because when I say it is easy to learn, it is, if you put in the time. Following are my suggestions for all you'll need to do to start playing the bass:
1. Place to practice, where you can play without distractions and practice every day.
2. Purchase a bass. If you want to play an acoustic bass, be sure that is what you want to play because acoustic basses are more expensive than electric basses. It all depends on your own taste and what kind of music and who you are going to play with. Start with a cheaper, but good quality bass. Check out the cheap bass guitar.
3. Start playing bass guitar, just to get the feel, it doesn't matter if you have never played before, you are just taking the first step to get the feel, because every bass guitar player has his or her own style and with playing bass guitar you will soon develop your own style.
4. Purchase an online lesson program to learn the basics. Playing bass guitar with an online bass guitar lesson program is the best way to learn on your own without costing as much as private lessons, see get started with online bass guitar lessons. Try not to learn from a friend because it can lead you to a style that is not yours, work on getting your own style. That is why I recommend playing bass guitar from a bass guitar lesson program.
