What Demo Files Are Available in Z-Tonnetz?

Z-Tonnetz ships with a built-in demo library that spans Baroque counterpoint, Classical sonatas, Romantic and Impressionist piano music, pop and rock hits, and game and stage music. You pick a file from the demo list and it loads for playback and visualization in the harmonic space, so you can watch chords, voice leading and key relationships unfold without importing anything. The list is a curated set of examples, not a complete catalogue of every piece named.

What the Demo Library Covers

The demos are grouped loosely by composer or artist in the list. The main clusters are:

• Bach: a large share of the library, including the Inventions & Sinfonias (complete), The Well-Tempered Clavier preludes and fugues (BWV 846–847), the English Suites (BWV 825–830), the Brandenburg Concertos (BWV 1046–1048), the Cello Suite Prélude (BWV 1007), the Chaconne (BWV 1004), Toccata and Fugue in D minor (BWV 565), Jesu, Joy of Man's Desiring (BWV 147), Erbarme dich, Ruht wohl and Wir setzen uns mit Tränen nieder from the Passions, O Haupt voll Blut und Wunden (two versions), the Lute Prelude in C minor (BWV 999), Sheep May Safely Graze, and the Air on the G String (BWV 1068).
• Beethoven: Für Elise and the Moonlight Sonata (1st movement).
• Mozart: Sonata K.545 (1st movement) and the Requiem movements (Introitus & Kyrie through Agnus Dei).
• Debussy, Ravel, Couperin, Villa-Lobos: Clair de Lune, Bolero, Les Baricades Mistérieuses, and the Bachianas Brasileiras No. 5 (Aria).
• Saint-Saëns: Aquarium and The Swan from Carnival of the Animals, plus Mon cœur s'ouvre à ta voix from Samson et Dalila.
• Vivaldi: Stabat Mater (RV 621) and The Four Seasons: Winter (1st movement).
• Tchaikovsky and Grieg: Flower Waltz; Morning Mood, Death of Ase, In the Hall of the Mountain King and Solveig's Song from the Peer Gynt suites.
• Pachelbel: Canon.
• Pop and rock: a-ha — Take On Me, Eagles — Hotel California, Toto — Africa, Radiohead — Creep, Dido — Thank You, Muse — Thoughts of a Dying Atheist, 4 Non Blondes — What's Up, Beatles — Because and Blackbird, and Max Martin — Baby One More Time.
• Game and screen music: Uematsu — Ahead on Our Way and Holding My Thoughts in My Heart, and Pokemon — Viridian City.

The page also notes that these are "all highly e…" (the excerpt is cut off), so treat the list as the starting set rather than an exhaustive one.

How to Use a Demo

1. Open Z-Tonnetz in the browser; the beta interface loads with Free Mode active.
2. Find the demo file list in the interface and choose a piece. Multi-movement works such as the Brandenburg Concertos, the Requiem or Peer Gynt appear as separate numbered entries, so select the movement you want.
3. Press Play. The piece loads into the player and the harmonic visualization responds in real time as it plays.
4. Adjust the view with the 2D, 3D, Torus, Leading Tones and Chords options to see the same music from different angles.
5. Change instrument, key (transpose), speed and volume from the controls if you want a different sound or a slower pass.

The expected result is that the selected demo plays and the chord and voice-leading motion is drawn in the harmonic space as it goes.

Choosing a Demo for What You Want to See

Common Snags

• Multi-movement works are split up. If a piece seems to start mid-work, you have probably selected a single movement entry rather than the whole set.
• SoundFont loading. The page warns that loading the SoundFont "should take less than 5 seconds"; if audio is silent right after selecting a demo, wait for that load to finish before pressing Play.
• Your own music. If nothing in the list fits, use Import MIDI to load your own file, or play your own keyboard and watch the visualization live.

The demo list is the fastest way to see what the 3D Tonnetz does with real repertoire before you bring in your own MIDI files.
