Musical Keys
In music theory, the key of a piece is the group of pitches, or scale, that forms the basis of a musical composition in Western classical music, jazz music, art music, and pop music. A particular key features a '' tonic (main) note'' and its corresponding '' chords'', also called a ''tonic'' or ''tonic chord'', which provides a subjective sense of arrival and rest. The tonic also has a unique relationship to the other pitches of the same key, their corresponding chords, and pitches and chords outside the key. Notes and chords other than the tonic in a piece create varying degrees of tension, resolved when the tonic note or chord returns. The key may be in the major mode, minor mode, or one of several other modes. Musicians assume major when this is not specified; for example, "this piece is in C" implies that the key of the piece is C major. Popular songs and classical music from the common practice period are usually in a single key; longer pieces in the classical repe ...

Music Theory
Music theory is the study of theoretical frameworks for understanding the practices and possibilities of music. ''The Oxford Companion to Music'' describes three interrelated uses of the term "music theory": The first is the "Elements of music, rudiments", that are needed to understand Musical notation, music notation (key signatures, time signatures, and Chord chart, rhythmic notation); the second is learning scholars' views on music from Ancient history, antiquity to the present; the third is a sub-topic of musicology that "seeks to define processes and general principles in music". The musicological approach to theory differs from music analysis "in that it takes as its starting-point not the individual work or performance but the fundamental materials from which it is built." Music theory is frequently concerned with describing how musicians and composers make music, including Musical tuning, tuning systems and composition methods among other topics. Because of the ever-expan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Modulation (music)
In music, modulation is the change from one tonality ( tonic, or tonal center) to another. This may or may not be accompanied by a change in key signature (a key change). Modulations articulate or create the structure or form of many pieces, as well as add interest. Treatment of a chord as the tonic for less than a phrase is considered tonicization. Requirements *Harmonic: quasi- tonic, modulating dominant, pivot chordForte (1979), p. 267. * Melodic: recognizable segment of the scale of the quasi-tonic or strategically placed leading-tone *Metric and rhythmic: quasi-tonic and modulating dominant on metrically accented beats, prominent pivot chord The quasi-tonic is the tonic of the new key established by the modulation. The modulating dominant is the dominant of the quasi-tonic. The pivot chord is a predominant to the modulating dominant and a chord common to both the keys of the tonic and the quasi-tonic. For example, in a modulation to the dominant, ii/V–V/V–V co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
