Changing tones. In music, changing tones (also called double neighboring tones and neighbor group) consists of two consecutive non-chord tones. [1] [2] The first moves in one direction by a step from a chord tone, then skips by a third in the opposite direction to another non-chord tone, and then finally resolves back to the original chord tone.
A nonchord tone (NCT), nonharmonic tone, or embellishing tone is a note in a piece of music or song that is not part of the implied or expressed chord set out by the harmonic framework. In contrast, a chord tone is a note that is a part of the functional chord.
The first tone of the Fundamental line. One of the three notes of the tonic triad, , or . See Schenkerian analysis:The fundamental line. Prolongation (German: Auskomponierung), Composing-out, Elaboration. The process in tonal music through which a pitch, interval, or consonant triad is able to govern spans of music when not physically sounding.
Schenkerian analysis is a method of analyzing tonal music based on the theories of Heinrich Schenker (1868–1935). The goal is to demonstrate the organic coherence of the work by showing how the "foreground" (all notes in the score) relates to an abstracted deep structure, the Ursatz.
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 ...
The composer and music theorist George Perle calls the whole-tone scale interval cycle 2, or C2. Since there are only two possible whole-tone-scale positions (that is, the whole-tone scale can be transposed only once), it is either C2 0 or C2 1. For this reason, the whole-tone scale is also maximally even and may be considered a generated ...
The notes used in music can be more complex than musical tones, as they may include aperiodic aspects, such as attack transients, vibrato, and envelope modulation. A simple tone, or pure tone, has a sinusoidal waveform. A complex tone is a combination of two or more pure tones that have a periodic pattern of repetition, unless specified otherwise.
In music theory, prolongation is the process in tonal music through which a pitch, interval, or consonant triad is considered to govern spans of music when not physically sounding. It is a central principle in the music-analytic methodology of Schenkerian analysis , conceived by Austrian theorist Heinrich Schenker . [ 1 ]
