Playing Section
  • 1

    Major chords form a downward triangle on the chart.

  • 2

    Minor chords create an upward triangle, differing by a flattened third.

Basic understanding of interval theory, particularly perfect fifths, major thirds, and minor thirds, which form the structural axes of the Tonnetz grid.
Fundamentals of chord construction, specifically how major, minor, diminished, and augmented triads are built.
Familiarity with the Circle of Fifths and how pitch classes relate to each other keys-wise.
A foundational grasp of the diatonic major scale, minor scales, and basic musical modes.
Neo-Riemannian music theory and the study of PLR (Parallel, Leading-tone, Relative) triadic transformations.
Application of the Tonnetz chart in film scoring and modern composition to create smooth, non-functional harmonic progressions.
Exploration of advanced geometric music theory, including representing pitch spaces as multidimensional tori or orbifolds.
Algorithmic composition and computational musicology utilizing coordinate-based pitch systems for generative music.

The Tonnetz chart is a visual tool that arranges the 12 chromatic notes in a grid where moving left to right increases by perfect fifths, moving diagonally up increases by major thirds, and moving diagonally down increases by minor thirds. This arrangement enables musicians to identify chord structures, scales, and intervals by recognizing geometric patterns: major triads form downward-pointing triangles, minor triads form upward-pointing triangles, suspended chords form horizontal lines, and symmetrical chords like augmented triads and diminished triads follow diagonal lines. The chart can be used to quickly determine chord members (major, minor, seventh, ninth, thirteenth), scale notes (major, natural minor, pentatonic), and modes (Ionian, Dorian, Phrygian, Lydian, Mixolydian, Aeolian, Locrian) for any key, making it a practical tool for understanding harmonic relationships and improvisation.
