The Academy's Board of Governors has approved Oscars rules and campaign regulations for the 91st Academy Awards. Among the new rules is the introduction of shortlists in the music categories. Opposed to previous years, there will now be two rounds of voting to produce the nominees, rather than a single round of nomination voting by members of the Music Branch.

In the first round, all members of the branch will view films eligible for Original Score and film clips of eligible Original Songs and vote in a preliminary round to produce a shortlist of 15 titles in each category using the preferential voting system. Five nominees for Original Score and five nominees for Original Song will then be chosen by branch members in a second round of balloting also using preferential voting.

For the complete 91st Academy Awards rules, visit The 91st Oscars will be held on Sunday, February 24, 2019, at the Dolby Theatre at Hollywood & Highland Center in Hollywood, and will be televised live on the ABC Television Network at 6:30 p.m. ET/3:30 p.m. PT.
