Rhythm and Logic

Requires fuller treatment — the concept currently rests on a single founding source.

Definition

Rhythm and logic is the pair of properties on which Wharton and Codman found the discipline of good design (1898): "all good architecture and good decoration (which, it must never be forgotten, is only interior architecture) must be based on rhythm and logic." The two terms carry two requirements. Logic is the functional-rational requirement: a house or room "must be planned as it is because it could not, in reason, be otherwise" — the plan compelled by purpose ("it must have a reason for being as it is and must be as it is for that reason"). Rhythm is the aesthetic yield of harmony: "from this harmony of the general scheme of decoration with the building, and of the details of the decoration with each other, springs the rhythm that distinguishes architecture from mere construction" — rhythm being precisely what separates designed work from mere building. The pair thus joins function (logic) and form (rhythm) as jointly necessary: neither decoration without rational plan nor plan without rhythmic harmony counts as architecture.

Key Thinkers

• Edith Wharton & Ogden Codman Jr — the pair's authors and the formula's coiners (1898/2006): rhythm defined as the product of two harmonies (scheme-with-building; details-with-details), logic as the plan's compulsion by reason.

Related Concepts

• the-double-test — the test the pair grounds: a feature stands only if it has a reason for being (logic) and harmonizes with the structure (rhythm's precondition)
• proportion — the deeper source of rhythm: since "decoration is always subservient to proportion," rhythm springing from harmony is ultimately proportional harmony
• interior-architecture — the formula's other half: decoration "is only interior architecture," so the rhythm-logic requirement is the discipline's founding standard
• suitability — the appropriateness-criterion the harmony requirement echoes ("the beauty of all such features depends on their appropriateness")
• style — style's proportional essence: conformity to style "is to accept those rules of proportion which the artistic experience of centuries has established as the best"

• The Historical Tradition (Wharton & Codman 1898/2006) — the concept's founding source: "Thus all good architecture and good decoration (which, it must never be forgotten, is only interior architecture) must be based on rhythm and logic. A house, or room, must be planned as it is because it could not, in reason, be otherwise; must be decorated as it is because no other decoration would harmonize as well with the plan" (p. 387); rhythm's two-harmony definition ("from this harmony of the general scheme of decoration with the building, and of the details of the decoration with each other, springs the rhythm that distinguishes architecture from mere construction," p. 387); the logic-qualification against literal structuralism ("Its decoration must harmonize with the structural limitations (which is by no means the same thing as saying that all decoration must be structural)," p. 387).

Open Questions

• Is "rhythm" in Wharton and Codman a proportional property (a rhythm of dimensions, per the proportion doctrine) or a temporal-perceptual one (the eye's movement through a room)? The text's two-harmony definition suggests the former; the proportion page's Summerson material would sharpen the question.
• The pair joins function (logic) and form (rhythm) in 1898 — decades before "form follows function." Does the founding formula anticipate the modernist dictum, or does its insistence on rhythm-as-harmony preserve a classical content the later functionalism discarded?
• Rhythm "distinguishes architecture from mere construction" — does the wiki's interior-architecture cluster (where the discipline's object ranges from shells to atmospheres) preserve or abandon this boundary-drawing use of the concept?
