In music, heterophony is a type of texture characterized by the simultaneous variation of a single melodic line. Such a texture can be regarded as a kind of complex monophony in which there is only one basic melody, but realized at the same time in multiple voices, each of which plays the melody differently, either in a different rhythm or tempo, or with various embellishments and elaborations ...
A pioneering system of plant taxonomy, Linnaeus's Systema Naturae, Leiden, 1735. This list of systems of plant taxonomy presents "taxonomic systems" used in plant classification. A taxonomic system is a coherent whole of taxonomic judgments on circumscription and placement of the considered taxa. It is only a "system" if it is applied to a ...
Introduction to Sousa's "Washington Post March", mm. 1–7 features octave doubling [1] and a homorhythmic texture.. In music, texture is how the tempo and the melodic and harmonic materials are combined in a musical composition, determining the overall quality of the sound in a piece.
Chart illustrating leaf morphology terms. The following terms are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (that is, the leaf blade or 'lamina' is undivided) or compound (that is, the leaf blade is divided into two or more leaflets). [1]
Homorhythm is a condition of homophony. [2] All voices sing the same rhythm. This texture results in a homophonic texture, which is a blocked chordal texture. Homorhythmic texture delivers lyrics with clarity and emphasis. Texture in which parts have different rhythms is heterorythmic or heterometric.
Linné's method for classification of plants in Classes Plantarum 1738, and the Figurative system of human knowledge from Diderot's Encyclopédie, 1752. Classification chart or classification tree is a synopsis of the classification scheme, [1] designed to illustrate the structure of any particular field. Classification tree.webm
Homophony began by appearing in sacred music, replacing polyphony and monophony as the dominant form, but spread to secular music, for which it is one of the standard forms today. Composers known for their homophonic work during the Baroque period include Claudio Monteverdi, Antonio Vivaldi, George Frideric Handel, and Johann Sebastian Bach.
The plant morphologist goes further, and discovers that the spines of cactus also share the same basic structure and development as leaves in other plants, and therefore cactus spines are homologous to leaves as well. This aspect of plant morphology overlaps with the study of plant evolution and paleobotany.
