Musical analysis Analysis is an activity most often engaged in by musicologists and most often applied to western classical music, although music of non-western cultures and of unnotated oral traditions is also often analysed. An analysis can be conducted on a single piece of music, on a portion or element of a piece or on a collection of pieces. A musicologist's stance is his or her analytical situation. This includes the physical dimension or corpus being studied, the level of stylistic relevance studied, and whether the description provided by the analysis is of its immanent structure, compositional (or poietic) processes, perceptual (or esthesic) processes (Nattiez 1990, 135â€“36), all three, or a mixture.
Musical instrument classification Later Sachs added a fifth category, electrophones, such as theremins, which produce sound by electronic means.[4] Modern synthesizers and electronic instruments fall in this category. Within each category are many subgroups. The system has been criticised and revised over the years, but remains widely used by ethnomusicologists and organologists.
