27 OPERATIONS / 27 KEYS

Your instrument

Hold a whole row0 / 27 held

Hold a button or its number key to play the chord; release to stop. These shortcuts work even when your keyboard cannot report many keys together.

Latch lets you build a chord one key at a time. Escape releases every note.
Choose a key. Imagine an operation.

Use your keyboard or touch the keys. Each form has its own key and pitch. Hold to sustain; release to let go.

Sound starts with your first key

Output delay appears after sound starts. For tighter timing, use built-in speakers or wired headphones.

INDEPENDENT TEMPOS · SHARED START

Rhythm mixer

Switch on up to six clocks. Each has its own tempo, metre and sound.

BPM counts individual beats. Beats per bar groups them. Tap a beat dot to cycle normal → accent → silent. Silent beats keep their place.

No recording yet

Your notes appear here as you play.

Records key presses and holds on this device. Maximum 3 minutes. Clocks stay separate from the recording.

DA VINCI · CROSS-DOMAIN IMAGINATION

One structure. Another world.

Imagine a world where these operations belong together. What changes if one starts later, overlaps, or stops?

How to play

1

Play a meaning

The top nine keys are archetypal. The middle nine are inner. The bottom nine are outer. Every key is a different form. Touch a key or press the letter shown on it.

For example, Outer Projection can be a source sending something out. Inner Projection can be a receiver taking something in. Build those roles into your imagined world.

2

Choose your time

Try one clock first. BPM means beats per minute; each clock accepts 1–240. Beats per bar accepts 1–16, including odd numbers. A 3-beat bar counts 1–2–3; a 4-beat bar counts 1–2–3–4.

Switch all clocks off for free timing. Use visual-only cues or alternating silent bars to practise maintaining the pulse yourself.

3

Reason, then perform

In Reason & play, read the clues and answer the missing-time question. Then try playing the score. A four-beat count-in prepares you. Beat 0 is the first beat after the count-in.

Play the named keys at their marked times. Hold a key for the marked length when a duration is required. Timing and note accuracy are reported separately.

4

Carry the world across

In World match, compare two complete worlds. Renamed entities and a uniformly faster or slower performance may match. The category, perspective, entity attachments, order and relative durations must all correspond.

Imagine the same system in a distant domain. Name what each part does and predict what happens if a timing relationship changes. A sequence alone does not establish cause and effect.

Keyboard map, audio and timing

Archetypal: Q W E R T Y U I O. Inner: A S D F G H J K L. Outer: Z X C V B N M , . These are physical key positions; on-screen pads also work. Keyboard playing pauses while you type in a field. Escape releases notes and cancels a performance or replay.

Audio uses a synthesised piano tone and six distinct metronome sounds. Wired audio or built-in speakers usually give more immediate feedback than Bluetooth. Timing results describe your input on this device; they are practice feedback, not a laboratory measure. Switching away from the page pauses the clocks and cancels an active performance so hidden time is not scored.

This is an experimental relational reasoning exercise. The ontology provides a vocabulary for constructing worlds; scores measure the displayed task, not intelligence.
