This is how Grammy Award winners are chosen

Submission:

The members of The Recording Academy and record companies enter music videos and pieces released during the eligibility year which they consider worthy of winning a Grammy award.

Screening:

The entries are then screened by more than 350 experts in various fields to make sure that the entered recordings meet the eligibility qualifications and are placed in the correct category such as jazz, pop, rock, contemporary, reggae, etc.

Nominating:

Now, the chosen entries are sent to voting members for the first round of nominations. To ensure that the quality of voting doesn’t fall short, members are directed to vote only in their areas of expertise; they may vote in up to ten categories up to three genres plus the six categories of the General Field (Record of the Year, Album of the Year, Song of the Year, Best New Artist, Producer of the Year, Non-Classical and Songwriter of the Year, Non-Classical). The ballots are tabulated by Deloitte.

There are special nominating committees for the Crafts categories as well and they comprise of voting members from all of The Academy’s Chapter cities who are actively involved in the craft that they are judging.

Final voting:

After the nominations have been determined, Academy members vote in up to ten categories across three genres plus the four categories of the General Field. Again, to ensure the quality, members are directed to vote for winners in those categories in which they nominated them.

Results:

The results are tabulated by Deloitte and Touche LLP. The winners are announced at the Grammy Awards premiere and telecast ceremonies. Ties are possible in which case the two [or more] nominees who tie are considered winners. Winners receive a Grammy Award and all nominees receive a nominee medallion and a certificate.

In addition to this, Grammy winners have to sign and agree to specific terms and conditions precedent to receiving a Grammy award statuette.
