nahyunk1 & yugyeonl Final

How to open up and run the file:

1. download and unzip the files below.
2. nahyunk1-yugyeonl-final project
3. songs
4. extract “sound1”, “sound2”, and “sound3” music files from the songs folder and put them into the “assets” folder inside the final project folder.
5. turn on terminal or node and run local server.
6. access the sketch.js inside the final project folder.
7. play and enjoy the songs by entering either 1, 2, 3 on your keyboard.

The project file was too large so we had to upload the songs separately in another folder along with the zip file of our code. Our project was based on the idea of generating animation with the kiwi bird and creating its walkthrough with the incorporation of music affecting the background of the landscape. There are three parts to the scenes: pressing 1 on your keyboard will affect your current scene to an urban landscape. Similarly, when either 2 or 3 is pressed, different scenes and music replace the current scene with different parts of the landscape responding to the beat, frequency, and the amplitude of the music assigned. The parts of the landscapes were drawn with the incorporation of the FFT(); function and the p5.Amplitude(); function which analyzes the frequency and the volume of the music when it is played. Some of the interesting factors that our animation consisted was the sun beam which would draw itself in an ellipse in a form of measured frequency and the stars and the moon which brightens and glistens depending on the beat of the music played at night. Throughout, we put a lot of effort learning and incorporating the p5.sound materials, creating a variety of landscapes with music chosen according to the mood of our scenes, and generally coding different functions and figuring out ways for our code to understand the switching of the scenes and the play of different music files.

**scene 2 consists of a song that is relatively louder than the other scenes that contain music files. We’ve put code for the sound of the song to be reduced, but the song still plays comparatively loud. Please be careful with the volume of your headphones.
