Beyonce performs in concert in Sao Paulo, Saturday, Feb. 6, 2010. Beyonce is on her first Brazilian tour and will perform in Florianopolis, Sao Paulo, Rio de Janeiro and Salvador.

Music plays a big role during presidential inaugurations. 

At what will be the 57th inaugural ceremonies, and President Barack Obama's second, Beyonce will sing the national anthem. Also performing at various festivities will be Brad Paisley, Stevie Wonder, Alicia Keys, the entire cast of the TV show "Glee."

It's a big gig for a musician for sure, and a tough one. After all you have to find just the right tone.

Music critic Steve Hochman has some thoughts on what these artists could and should perform.
