there are four major parts to the contemporary carnaval, all building into one another and creating an unique synergy of festivities.

most famously, the parades of the world-renown samba schools competing at the sambódromo, an oscar neimyer-designed, purpose-built open-air amphitheater on avenida trinta e um de março which after its remodel in anticipation of the 2016 olympics now seats 90,000 people.

then, the multitude of spontaneous, organized, and semi-organized street parties (known as blocos) that spring up in every neighborhood and on every corner, drawing neighbor and traveler alike into the all-encompassing embrace of the samba rhythm.  

also gaining popularity are the many masquerade balls (bailes) throughout the city, ranging from small, intimate gatherings thrown by neighborhood associations and clubs to the legendary and lavish magic ball at the copacabana palace hotel.
