1. Remix the Dance Party Starter Project


(upbeat music)

Hey, and welcome to Scratch Music.

Today you'll learn how to use a forever loop and explore how to create movement in Scratch while building a dance animation.

Today you'll learn about an important computer science concept; loops.

A loop is simply a set of instructions that repeats over and over.

At many computer science concepts, loops exist all around you.

In music, repeated musical phrases are called ostinatos in appearing throughout a song, like the repeated notes in the famous Jaws scene.

(Jaws theme music)

Advanced choreography also contains excessive repeated movements that are like loops.

Even your daily routine can be seen as a repeating set of instructions, such as: getting up, eating breakfast, going to school, coming home, and going to bed.

You will repeat those same set of instructions the next day and the day after that.

Repeat forever loops tell the computer to follow the same set of instructions over and over again.

In today's dance party project (hip-hop music)

you use forever loops to make Cassy dance forever to music that never stops playing.

You use a forever loop to make both the music play, and to make Cassy dance.
