iPhone Project Proposal
Chris Bigart

I plan to write an application to assist users with identifying musical notes and chords.  The 
application will play a note and give the user a number of options to correctly identify the 
note or chord.  In this manner, the user can learn to train his or her ear to identify a 
variety of notes and chords.
Some background information: notes are a sound of a certain frequency.  The note `A', for 
example, occurs at a frequency of 440 Hz.  It also occurs at logarithmic intervals of this 
frequency such as 110 Hz (440 * 2), 220 Hz (440 * 2), 880 Hz (440 * 21), 1660 Hz (440 * 22), 
etc.  Chords are simply a combination of three or more notes played in unison.  An `A Major' 
chord would consist of the notes A, C#, and E.
The application will track the accuracy of the user over a period of time to monitor his or 
her progress at identifying notes and chords.  This data could be sent to a backend database 
for storage, and potential later retrieval and analysis.
The GUI for the application will consist of a selection screen where the user may choose which 
set of notes or chords to practice identifying.  Once this selection is made, the interface 
will change to the main screen.  From here, a note or chord will be played via audio while the 
screen will display a number of buttons each with a possible note or chord name.  The user 
will select one of these buttons, and the program will respond by notifying the user that the 
choice was either correct or incorrect, then the next note or chord will be played.  This will 
continue indefinitely until the user either exits the program or exits to some sort of main 
menu.
This program will facilitate and hopefully ease the memorization of notes and chords.  
Musicians should find it to be a helpful learning tool.
