Learning to sing acapella isn't that different from learning to sing with download acapellas instrumental accompaniment.Just as in acapella singing, you'll need to have some sort of understanding of the singing voice, getting a beautiful singing tone, how to sing on pitch, etc. In fact, being able to sing on pitch is the biggest challenge that acapella singers and groups face because there's no music supporting them.Let's assume that you know nothing about singing and you'd like to learn how to sing and then eventually move into singing acapella, whether it be for solos, choirs, barbershop groups or whatever.
The first step you'll need to take is to find a fantastic vocal coach. The best place to look for a singing instructor is at the nearest university or college that has a music program in place. Simply walk in to the music department and ask the secretary to give you the contact info for head of the vocal department and a couple of the best teachers there. Actually, you won't know if they're any good until you've tested them.
Here's the thing there are a lot of really crappy voice teachers out there. True story. And an incompetent voice teacher can do a lot of damage. Not only will they take your precious time and hard earned money, they will stall your progress, create great frustration in your singing efforts and in a worst case scenario, do irreparable damage to your voice.
