The convention hall will have two musical stages — one for surprise acts and another for the house band, which will be led by G. E. Smith, the former musical director for “Saturday Night Live” and guitarist for Hall & Oates.

To serve as executive producer, the Republican Party brought in Phil Alongi, a former politics producer with NBC News. Mr. Alongi has helped the Romney campaign fine-tune its programming so it fits neatly into the tight, one-hour block that the broadcast networks have dedicated to airing the convention in prime time. He has advised them on how to avoid certain pet peeves of producers, like running long at the top or bottom of the hour, when the networks have to cut away for commercial breaks.

Mr. Alongi, with his knowledge of what cameramen and producers will be looking for, has also ensured that Republican Party branding is placed in camera lines of sight. “When they’re flipping through the channels at home, I want them to know this is the Republican National Convention,” he said.

The most ambitious element of stagecraft, however, will be the podium — which features 13 different video screens — the largest about 29 feet by 12 feet, the smallest about 8 feet by 8 feet and movable. All the screens will be framed in dark wood.

“Even the frames are designed to give it a sense that you’re not looking at a stage, you’re looking into someone’s living room,” said Russ Schriefer, one of Mr. Romney’s senior advisers who is running the convention planning for the campaign.
