=== Fux's Voice Leading Rules ===
The table below describes voice leading rules in terms of intervals, or just two notes. Each note of the current interval will either move or remain constant in order to form the destination interval. Depending on the type of current (source) and destination intervals desired, there will be certain preferred types of motion.

! !! Interval<br>Type !! Perfect !! Imperfect
|-
!rowspan="2"| CurrentSource
! Perfect
|
These can be reduced to 2 simple rules:
# If the destination interval is ''perfect'', only contrary or oblique motion can be used.
# Parallel motion can only be used if the current source and destination intervals are ''imperfect''.
If "perfect/imperfect" is confusing in describing the intervals, see the table below. The only '''perfect intervals''' are the perfect 4th, perfect 5th, and unison (or octave).

=== Additional Rules ===
* The leading tone should always resolve up to the tonic if the tonic is part of the next chord.
* Smaller movement is preferable to larger movement.

== Application to Guitar ==
* A few cases have similar motion of two low notes to the same bass notes. This forms a P1 interval, which should not be led by similar motion; however, the alternative is to use inverted chords, which we are avoiding for clarity at this time.
* The chord shapes contain numbers indicating the scale degrees of the notes that comprise the chord. Notice all the tonic chords use (1, 3, 5), the ii chord uses (2, 4, 6), etc.
