HOW IT WORKS
A basic, but important tool for visualizing the notes being played. Great for training yourself to stop staring at your hands while playing.

Circle of Fifths
The Tonnetz is a 2-dimensional mesh that illustrates spacial representations of tonal distance and relationships. Think of it as adding another dimension to the Circle of Fifths. In fact, if you start on any note and continue down the right path you are essentially going around the Circle of Fifths. Similarly, each branch off of a note represents a different interval (bottom right – major 3rd, top right – minor 3rd, etc).
Check out this article by Josh Walsh for an excellent breakdown of what you can learn from the Tonnetz.
