Parallel 5ths and parallel 8ves are forbidden.
Hidden 5ths and hidden 8ves are forbidden. **

** This rule is relaxed for the inside voices in 4-part writing.
Contrary motion is best.
Limit chains of parallel 3rds or 6ths to no more than 4 in a row.
Use caution if both voices leap in the same direction at the same time. If both do leap at the same time, neither voice can leap more than a 4th.

** One exception is the ‘leap’ of an octave - this is treated more like a repetition than a leap.
Voice crossing is permissible in this style, but should be limited.

For our purposes today, it is best to avoid it altogether.
