## Making the Rule Do the Work

The three key conceptual tools in a studio are the **series**, the **constraint** and the **system**.

### Series

A series holds one element fixed and varies another. Monet showed fifteen *Meules* canvases at Durand-Ruel in May **1891**. Twenty *Rouen Cathedral* paintings followed in **1895**.

Fixing the motif makes the shifting light visible. The series **is** the work; no single canvas carries the argument alone.

### Constraint

A constraint is a rule set beforehand that removes routine decisions. It leaves only the essential choices to make.

* **On Kawara** began the *Today* series in **1966**. Each date painting had to be finished by midnight or destroyed.
* **Roman Opalka** started in **1965** painting numbers from 1 upwards. In **1972**, he began adding one per cent white to each new ground.

### System

A system is a constraint that fully enumerates the work.

* **Sol LeWitt** explored *Incomplete Open Cubes* in **1974**, finding exactly **122** variations.
* **Gerhard Richter** generated colour charts using mixing rules.
* Combining four hues, three values and two formats yields 4 x 3 x 2 = **24** canvases.

| Tool | What is fixed | What is variable | When it ends |
|---|---|---|---|
| **series** | Motif or format | One chosen condition | By judgement |
| **constraint** | A prior rule | What the rule leaves open | By the rule |
| **system** | Generating procedure | Nothing (enumerable) | When exhausted |

### Where the Work Lives

A strict Rule creates interest through human friction. With Opalka and Kawara, human limits meet mechanical rules across decades.

> **Common pitfall:** quietly breaking a rule when it gets inconvenient. If a rule must change, change it explicitly and close the previous set.

## Practice questions

8 of this lesson's 14 practice questions, with answers. The full set is in the app.

### 1. Why does each of these produce a body of work rather than a single picture? Sort by the kind of tool it is.

**Answer:**

- A series: one thing held, one thing varied: Haystack by hour, Doorway monthly
- A constraint: a rule adopted in advance that removes decisions: Single-day limit, Lose one colour
- A system: a procedure whose members can be enumerated: Mix-rule colours, Hue-value combos

**Why:** The third column is the one with a definite end. A system tells you before you start how many works there are and when you have finished, which is a strange and useful property: the painter is relieved of the decision about when to stop, and the viewer can see the whole shape of the thing.

### 2. A series is a set of attempts at one picture, continued until one of them succeeds.

**Answer:** False

**Why:** **False**, and it inverts the idea. The series is the work, and no single canvas in it carries the argument, which is why they were exhibited together. Holding the motif fixed is what makes the variable visible, and a single canvas has nothing to be visible against.

### 3. In conceptual studio practice, a system is distinguished from an open constraint by full enumeration. What does this distinction require of the artist's role once execution begins?

A. They must step away entirely to let an assistant make it.
B. They must decide when variations have made the point clear.
C. They must adjust the procedure to avoid repetitive outcomes.
D. They must eliminate all unprescribed compositional choices.

**Answer:** D. They must eliminate all unprescribed compositional choices.

**Why:** A system exhausts every permutation defined by its generating procedure, leaving no room for subjective compositional edits during production. Relying on judgement to stop confuses a system with an open series, whilst altering rules mid-run breaks the logic that defines systematic work.

### 4. Complete the account of series and system.

**Answer:** Fifteen of Monet's Meules were shown at Durand-Ruel in **1891**. On Kawara began the Today series of date paintings in **1966**. Sol LeWitt's Variations of Incomplete Open Cubes arrives at **122** distinct arrangements. Richter's colour charts of the early 1970s are generated by mixing rules rather than **chosen**.

**Why:** The last blank is the whole argument in one word. Once a generating rule is in place the individual colours are not chosen, so the charts cannot be read as taste; what is left to look at is the rule, the mixing, and the fact of a painter carrying out a procedure by hand.

### 5. A series is defined by four hues, three values and two formats, with exactly one canvas for every combination. How many canvases does it contain?

**Answer:** 24

**Why:** **24 canvases.** The number is knowable before a single one is made, and that is what a system buys: the painter is relieved of deciding when the work is finished, and the viewer can tell whether they are looking at all of it or at a selection from it.

### 6. Arrange the steps of setting up a rule-governed series in the order they must be settled.

**Answer:**

1. State what the work is trying to make visible
2. Decide what will be held constant so that it can be seen
3. Decide what will vary, and over what range
4. Fix the format, the palette and the schedule by rule so they stop being decisions
5. Write the rule down and date it, so that any later change is visible as a change

**Why:** The last step is the one that separates a system from an intention. A rule that only exists in the painter's head can be amended silently at the difficult point, which is exactly when it was about to do its work, writing and dating it turns a later change into an event rather than a lapse.

### 7. Which of these are true of On Kawara's Today series?

A. A painting not completed by midnight of that day was destroyed
B. The paintings were made in a single studio over a fixed period of months
C. It began in 1966
D. Each painting names the date on which it was made

**Answer:** A. A painting not completed by midnight of that day was destroyed; C. It began in 1966; D. Each painting names the date on which it was made

**Why:** The fourth is wrong in a way that matters. The paintings were made in whatever city the artist was in, and the language and date convention follow the place, which is why the series is a record of a life's movement as well as of its days, and why a fixed studio would have destroyed half its content.

### 8. Sol LeWitt's Variations of Incomplete Open Cubes arrives at 122 distinct arrangements.

**Answer:** True

**Why:** **True**, and the number is a finding rather than a choice. Once "incomplete" and "three-dimensionally distinct" are defined, the count follows, and the artist's job becomes execution and presentation. That is exactly what distinguishes a system from a series that merely feels systematic.
