Tonnetz

The Tonnetz is a visual and conceptual tool in music theory that maps out the relationships between pitches, chords, and keys. It arranges notes in a grid or lattice where neighboring points relate through common musical intervals, such as fifths and thirds. This helps musicians see and understand how chords and melodies connect and transform, highlighting harmonic relationships and tonal centers. Think of it as a map that illustrates the interconnected landscape of musical harmony, making complex relationships more intuitive for analysis and composition.
