EarThoseChords is a tool to help musicians learn to 
recognized the root of chords based on it's distance 
from the tonic of the key.  The motivation for this 
code came from the success the author has had learning 
melodic dictation using Alain Benbassat's method (as 
found in the Android App "Functional Ear Trainer" by 
Serhii Korchan).  
If you enjoy this software, please consider making a 
donation to Alain Benbassat on his website www.miles.be
