A symphony of explosions
The mascletá is a (mostly) daytime firework show consisting on rythmic sound explosions. It is based in the use of the so-called ‘masclet’ (a kind of powerful firecracker), whose explosion receives the name of ‘thunder’. The word’s etimology lies in the Valencian word for ‘male’. It is probably related to the loudness of the sound, what was considered masculine, and to the fact that these fireworks explosions were dedicated exclusively to holy men; whereas celebrations for holy women had a lighter, more feminine character. The origin of the mascletá lies probably in the purifying character of black powder, to scare evil spirits. Today, mascletás are common in weddings and other celebrations.
The mascletá is a very austere show, it has no colours or shapes to decorate, it is based on the beauty of the pure explosion. It normally lasts for 5 to 10 minutes and follows a strict order. In this sense, we can consider them authentic symphonies of noise.

Schedule of a mascletá, as proposed on the book 'Pirotecnia en Valencia' of Ferriols, Pagola and Solá
For the mascletá, the masclets are connected by a thread structure at about 2,5 meters height. The mascletá seeks rythm and growing intensity, combining ground and air explosions, and has its summit with a deafening ground explosion called ‘earthquake’ and an explosion in the air called ‘bombardment’. The mascletá ends with the ’signature’.

In March, during the Fallas celebrations of Valencia, the public can enjoy big mascletás in the city hall square. These overwhelming mascletás are held daily at 14.00h by a different pyrotechnic and increase their intensity as days pass by. This video courtesy of Freakpyromaniacs (7′31”) shows the mascletá by well-known pyrotechnist Ricardo Caballer that took place on March 19, St Joseph’s Day, last day of the Fallas 2009. Because of its filming angle, it allows to see very well all phases of the mascletá. Definitely worth watching till the end, to understand the magnitude of this traditional celebration and share the mascletá’s intense emotion that lets visitors speechless, and often highly addicted.
