I don't need to read music to understand it.... I play in an open D tuning and didn't know how to play 7ths, 9ths, etc. I use EZ Key to help me find the notes for the chords I need to play. Over time, I have found I'm doing the same thing to find different information, and I've notice how it all relates now.

As a songwriter, I have found EZ Key to be an invaluable tool. I use it for everything from determining the key of a song, to learning the chords in that particular key, to aiding in the tempo and timing of the song. Though I have been writing music for over fifteen years, I have only recently begun to play guitar. EZ Key has been such a blessing, aiding in the learning process and guiding me toward better, easier songwriting. No more lugging around huge books and looking up keys, chords and notes. One simple and small tool does it all!
