In quantum chemistry, size consistency and size extensivity are concepts relating to how the behaviour of quantum-chemistry calculations changes with the system size. Size consistency (or strict separability) is a property that guarantees the consistency of the energy behaviour when interaction between the involved molecular subsystems is nullified (for example, by distance).
Gordon music-learning theory is a model for music education based on Edwin Gordon's research on musical aptitude and achievement in the greater field of music learning theory. [1] [2] The theory is an explanation of music learning, based on audiation (see below) and students' individual musical differences. The theory takes into account the ...
While formal music education has roots going at least as far back as the Hebrews in Egypt [2] or the ancient Greeks, [3] challenges arose as music became more specialized and technically complex after the 5th century BCE in Ancient Greece and as the development of notation shifted music education from training in singing to training in music reading.

Music education is a field of practice in which educators are trained for careers as elementary or secondary music teachers, school or music conservatory ensemble directors. Music education is also a research area in which scholars do original research on ways of teaching and learning music.
The Oxford Companion to Music describes three interrelated uses of the term "music theory": The first is the "rudiments", that are needed to understand music notation (key signatures, time signatures, and rhythmic notation); the second is learning scholars' views on music from antiquity to the present; the third is a sub-topic of musicology ...
Musical symbols are marks and symbols in musical notation that indicate various aspects of how a piece of music is to be performed. There are symbols to communicate information about many musical elements, including pitch, duration, dynamics, or articulation of musical notes; tempo, metre, form (e.g., whether sections are repeated), and details about specific playing techniques (e.g., which ...
Some intensive properties do not apply at very small sizes. For example, viscosity is a macroscopic quantity and is not relevant for extremely small systems. Likewise, at a very small scale color is not independent of size, as shown by quantum dots, whose color depends on the size of the "dot".
Basic Concepts in Music Education is a landmark work published in the USA 1958 as the Fifty-Seventh Yearbook of the National Society for the Study of Education. In 1954, the Music Educators National Conference ( MENC ) had formed its Commission on Basic Concepts in an attempt to seek a more soundly-based philosophical foundation.
