A marble vault plays a two-chord cadence. Slide the gold pin into Authentic (V–I), Plagal (IV–I), Deceptive (V–vi), or Half (I–V). The slots are physical tumblers on the door, not a quiz list. A wrong tumbler Jams and sparks. Eight Latches open the vault.
Open the vault
Pick Easy, Medium, or Hard, then Slide. Two chords play. Tap Hear if you need them again.
Read the tumblers
Easy shows Authentic (V–I) and Half (I–V). Medium adds Plagal (IV–I). Hard adds Deceptive (V–vi).
Slide
Drag the gold pin into the tumbler that matches the cadence. A seated pin adds Score and Streak. A miss is a Jam.
Clear 8 Latches
Finish 8 Latches for Vault open, or keep going until the pins go dark. Vault jammed shows Score, Streak, and Slide again.
Slide the gold pin
A cadence plays. Drag the pin from the felt well into a marble tumbler. Authentic is V–I. Plagal is IV–I. Deceptive is V–vi. Half is I–V.
Tumblers, not a list
The vault door holds the slots. A right Slide seats the pin. A wrong tumbler Jams, sparks, and sends the pin home.
Score, Streak, Latches
Eight Latches open the vault. Each seated pin grows Score and Streak. Three gold lives. Hear replays the cadence.
More cadences on Hard
Easy is Authentic vs Half. Medium adds Plagal. Hard opens all four: Authentic, Plagal, Deceptive, Half.
Cadence Latch is a high-school harmony game. A marble vault plays a cadence. The player Slides a gold pin into Authentic (V–I), Plagal (IV–I), Deceptive (V–vi), or Half (I–V). The slots are tumblers on the door. Easy is Authentic vs Half. Medium adds Plagal. Hard uses all four. Eight Latches finish the run. It is a physical latch, not a four-button theory worksheet.
Hear, then Slide
Students name a cadence by seating a pin, not by tapping a card. V, I, IV, and vi stay on the tumblers as theory symbols.
Skill grows with the door
Easy is two cadences. Medium adds Plagal. Hard adds Deceptive. The vault changes, not only the clock.
Jam or seated
A hit seats the pin and grows Score and Streak. A miss Jams the tumbler. The board and the how-to share Slide, Authentic, Plagal, Deceptive, Half, and Latches.
Finger or mouse
Drag the pin. Tumblers stay large. Hear replays V–I, IV–I, V–vi, or I–V without leaving the door.
Authentic is V–I. Plagal is IV–I. Deceptive is V–vi. Half is I–V. Those symbols stay untranslated on every tumbler.
