When you compare the Harmonizer to other reference tools you will discover how comprehensive it is. I crammed as much musical information in it as I could. It's like a semester's worth of musical instruction for the price of one music lesson.

The chart below compares the features, in my opinion, of four of the best musical reference tools on the market. Check it out and decide which one is best for you.
A. The Harmonizer by Lotus Music
