The tiles falling toward you are chord names, press the full triad in time as each one lands.
A chart of named chords scrolls down a keyboard lane. As each chord reaches the hit line you must press every note of its triad or tetrad at once. Nail chords on time to build your score; miss the timing and you lose the hit. It is sight-reading and timing rolled into one.
Cadence Keys fuses falling-tile rhythm play with real chord reading, pairing timing with harmony.
Pressing every note of a triad or seventh chord at once as it reaches the hit line is chord recognition converted into a physical shape.
Requiring the whole chord simultaneously is the original demand.
Playing a chord is not playing its notes quickly. The hand has to arrive as a unit, which is why chord shapes are learned as shapes — and why the four-note tetrads are a genuine step up rather than one more note.
Cadence Keys is an original, free browser game that fuses falling-tile rhythm play with real chord reading. It is built in-house and needs no install.
