(upbeat pop music)
Welcome back to CS First Scratch Music and Soundwhere you can use computer scienceto make creative projects involving sound.
Today you will make a DJ mixing tool.
DJ's use scratching techniques and digital mixingboards to build their own music.
They incorporate sounds sampled from other songsand mix them to a beat that people can dance to.
During a dance party, DJ's use mixing boards to adjusttheir music choices, sample selections,and scratching techniques to engage an audience.
DJ's even battle at worldwide events where they are givena limited amount of time, usually anywhere from 30 secondsto a couple of minutes to show off their skills.
But did you know that the mixing board that makesall of this possible is actually a type of computerthat uses technology built my computer scientists.
