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.
