One use of first inversion is to smooth out the bass line.
（第一转位的一个用途就是平滑低音线）By placing this chord in first inversion, the bass line becomes smoother.
（随着这个和弦变为第一转位，低音弦变得更加平滑） |
We can also use first inversion when repeating a chord.
（当重复和弦时，我们也可以使用第一转位）Instead of altering the top voices, the chord is placed in first inversion.
（最高音保持不变，将和弦变为其第一转位即可） |The diminished triad presents the final use for first inversion.
（减三和弦表示第一转位的最后一种用法）Early composers did not like using augmented or diminished intervals.
（以前，作曲家们不喜欢使用增减和弦）Notice that a root position diminished triad contains a diminished fifth.
（这个减三和弦的基本音位包含一个减五度）The second inversion of the same triad contains an augmented fourth.
（第二转位包含一个增四度）Only the first inversion contains no augmented nor diminished intervals.
（只有当在第一转位时，音程不增也不减）Because of this, composers prefer first inversion diminished triads.
（这样，作曲家们会在使用减三和弦时使用转位代替）
