Description:

Dancing Note Composer (DNC) is a program that allows the user to use their computer keyboard as a proxy to the on-screen keyboard, to compose music. It then allows them to play back their music. As it plays each note, the note �dances� (which, as my roommate so kindly stated, looks like the notes are popping out of the screen to punch you in the face. ).

Goals:

Create hierarchical models for a bar of music, including the treble clef, and all composed notes

Create hierarchical models for whole, half, quarter, eighth, and sixteenth notes, including sharps.

Create an interactive hierarchical model of a single octave of a piano keyboard, complete with white and black keys

Allow a user to compose a piece using the virtual piano and input from the computer keyboard.

Allow a user to playback a composed piece, and make the keys press and the notes dance as you do so

Create different materials for different pitches, to differentiate them.

System Requirements:

You must be running an Intel Mac (which should have the afplay command-line audio player) (The program will work, but it won�t play music if you don�t have afplay)

You must the folder ~/Desktop/CPE471/Final_Project_Files/note_waves_short/ , and then fill that folder with the provided WAV files

Provided:

The Xcode Project �Keyboard�.

To run the program, open this in XCode and press the �Build and go� button.
