Segmentum notarum septem in C7 circulo intervallium.

Reticulum Klumpenhouweranum, ex Henrico Klumpenhouwer, theorista musicus Canadiensi et olim discipulo doctorali Davidis Lewis in Universitate Harvardiana appellatum, est "quodque reticulum quod operationibus T et/vel I (transpositione vel inversione) utitur ad interpretandas coniunctiones inter copias classium soni.[1][2] Secundum Georgium Perle, "Reticulum Klumpenhouwerianum est chorda per eius summas et differentias dyadicas" explicata, et "hoc genus explicationis coniunctionum triadicarum in notione copiarum cyclicarum ab initio intellegebatur,[3] in quo copiae cyclicae sunt copiae quarum elementa alterna complementarios unius intervalli circulos aperiunt."[4]

"Notio Klumpenhouwerana, in eius significationibus ambo simplex et profunda, est quod sinit coniunctiones inversionales una cum transpositionales in reticulis sicut eis figurae primae,"[5][2] quae sagittam monstrat desuper a B ad F# nominatum T7, desuper a F# ad A nominatum T3, et sursum ab A ad B, nominatum T10, quod sinit ut repraesentatur a figura 2a, exempli gratia, nominatum I5, I3, et T2.[2] In figura 4, hoc est (b) I7, I5, T2 et (c) I5, I3, T2.

Coniunctiones K-net, inversionales et transpositionales, sagittis, litteris, numeris repraesantatae. Chorda 1.
Inversionales K-net coniunctiones,sagittis, litteris, numeris repraesantatae. Chorda 1.
Chorda 3, quae cum chorda 1 est exemplum regulae primae.
