A '''friend''' here is defined as a note separated from the starting note by either a close approximation of an [[LCJI]] interval, or else, a close approximation of a [[Delta-rational chord|delta-rational]] interval, without being too close to one another in acoustic proximity. Friends are most frequently prefect consonances, such as [[3/2]] or [[4/3]], imperfect consonances such as [[5/4]] or [[8/5]], or ambisonances such as [[7/4]] and [[8/7]]. However, sometimes imperfect dissonances also meet the definition of a friend, for example, neutral third like [[11/9]].

An '''enemy''' is defined here as a note separated from the starting note by an interval that causes intense discordance, or else, does not easily connect the two notes through LCJI or through delta-rational relationships. It should be noted that perfect dissonances are always enemies, but imperfect dissonances sometimes also meet this ~~criteron~~. Furthermore, some notes can be called "''frenemies''" since they meet the definition of an enemy only part of the time.

The phenomenon of '''crowding''' is a major source of dissonance, specifically, it results when an interval separating two notes is either too small or too close to an octave-reduplication of the starting note.
