What is common practice for four part voice leading for the N6?
When voice leading the N6 in four part writing, it is common practice to double the bass of the chord and while using contrary or oblique motion within the upper voicings. A resolution to a V7 can utilize common tones when voice leading and can eliminate any parallel octaves that occur with a double bass.
What is the common practice for voice leading a N6 chord to the V7?
When voice leading from an N6 to the dominant, it is also possible to delay the resolution slightly by using a cadential 6/4 chord. Although the cadential 6/4 is based off of the tonic, the 6/4 inversion helps it to function more as a precursor to a dominant movement. However be sure to avoid parallel fifths when voice leading this progression.
