Ask a musician what his style of music is, and he'll usually answer "I don't know, it's hard to explain – we do a little bit of every style".

While I respect a musician's right to eclecticism, there are a lot of positives to being incredibly narrow in what you offer customers. Here's five of my top reasons why you should go narrow:

5. you'll stand out. In a crowded market, being the "expert" in a specific field gives you serious street cred, and separates you from your competition in the minds of your customers.

4. people will trust you more. If you're confident enough to refer people to your competition if you don't offer what they need, your customers are going to trust that you have their best interest in mind. Pluses for you: you'll become the go-to contact guy of your industry (good for a ton of reasons), and a bunch of your musician friends will owe you big favors for all the gigs you hooked them up on. 

3. Every time someone wants what you're offering, they'll think of you first.  If you're selling yourself as the everything-fits-all option, there will be no single distinctive feature that will stand out to your customers. Humans remember specifics and extremes. If you communicate neither to the customer, it's time to go narrow. 

2. You'll get better at what you do.  Relentlessly focusing on being amazing in one area will usually. . . make you amazing in that one area. Big surprise.  

1. You'll be happier. If you pick a skill you're good at and enjoy, you're probably going to love working in the field you've chosen. And since you'll be so much more successful than before you got narrow, you'll most likely be happier, too.
