In music, a factor or chord factor is a member or component of a chord. These are named root, third, fifth, sixth, seventh, ninth (compound 2nd), eleventh (compound 4th), thirteenth (compound 6th), and so on, for their generic interval above the root.In harmony, the consonance and dissonance of a chord factor and a nonchord tone are distinguished, respectively.

  • In music, a factor or chord factor is a member or component of a chord. These are named root, third, fifth, sixth, seventh, ninth (compound 2nd), eleventh (compound 4th), thirteenth (compound 6th), and so on, for their generic interval above the root.In harmony, the consonance and dissonance of a chord factor and a nonchord tone are distinguished, respectively. Chord factors are taken into consideration in voicing and voice leading. A chord contains exactly as many factors as it contains unique pitch names (octaves don't matter), while a voicing can have any number of voices that draw from and represent some or all the factors of a chord in various octaves. Thus, a chord with three unique pitch names always has three factors, even if some of those pitches are doubled or omitted in a particular voicing. For example, the figure to the right shows a four-note voicing of a C Major triad, which has three chord factors. The "root" chord factor (pitch name "C"), is represented twice in the voicing by voices 1 and 4 in different octaves. The chord factor called the "fifth" (pitch name "G") is represented in voice 2 (shown in red). The chord factor that is in the bass determines the inversion of the chord. For example, if the third is in the bass it is a first inversion chord (figured bass: 63) while if the seventh is in the bass the chord is in third inversion (42). The illustration shows one possible four-note voicing of a G7 third-inversion chord (written G7/F in lead-sheet chord-symbol notation), with every chord factor being represented once by a voice in the voicing. In Tertian harmony, chords are made more complex, or "extended", by introducing additional chord factors stacked in thirds. The illustration shows the theoretical construction of a C13 chord having seven chord factors, with the "extended" chord factors shown in red. In real applications, it is common practice to omit the eleventh from voicings of a dominant 13 chord, because though being necessary to theoretically derive the thirteenth by stacking on it, the unaltered perfect eleventh clashes with the major third.

  • 在音乐中,和弦因素是指一个和弦中所在某个位置的音。具体形容方式如下 “根音(一音)” , “三音”,“五音”,“六度音”,“七音”,“九音”,“十一音”, “十三音”等等。通过以根音(一音)向上到目的音的音程而命名。在和声中,与非和弦音所产生的的效果非常明显。和弦因素经常在以及的创作中被考虑。一个和弦包含绝对的和弦因素,此特性与和弦有其绝对的根音高度的特性是相似的,八度不参与讨论(因为在分析时所有十二平均律中重复的音都被缩减到一个)。正因为缩减的原则,一个在十二平均律中含有三个不同根音高度的和弦,通常含有三个和弦因素(讨论和弦因素时包括了根音)。在右侧的例子中表示了一个由四个音组成的C大调和弦,其中包含三个和弦因素。其中,“根音”的和弦因素(音:“C”)在(从下往上数)第一以及第四层都出现过,它们所在两个不同的八度。和弦因素“五音”(音:“G”)出现在第二层(已用红色标出)。低音的和弦因素决定了和弦的转位。比方说:如果原和弦的三音(从下往上数第二个音)是低音(最下方的音),那么这个和弦是原和弦的第一转位;如果原和弦的七音(第四个音)是低音(最下方的音),那么这个和弦是原和弦的第三转位。插图说明了一种G7 和弦(G大调七和弦)第三转位可能出现的情况(此和弦的简写形式为 G7/F ),此种情况每一个和弦因素都会至少在和弦中出现一次。 相对于[[Tertian|]]的和声而言,和弦会变得更加复杂,甚至会发生更改原和弦三音从而扩展和弦的情况。插图说明了这种理论(一个 C13 和弦(C大十三(扩展)和弦)通过添加七级和弦因素从而扩展和弦,扩展部分已用红色标出。)在实际应用当中,通常做法是将属十三和弦的十一音忽略掉,从而在上方延伸出十三和弦,避免十一度音与大三度音发生冲突。 (zh)
