	This concept is mostly relevant when applying extreme tunings to abstract scales, causing some steps to have a negative size in order to preserve the abstract scale's usual structure. For example, if you try to generate a [[MOS scale]] with a [[generator]] whose size falls outside of the generator range of all possible MOS patterns with the same given number of notes, you should obtain a negative MOS scale. A 7-tone scale with a 295{{cent}} generator is just outside of the range for [[4L 3s]], and can be interpreted as a 4L 3s scale with 315{{cent}} large steps and -20{{cent}} (negative) small steps.

	A [[tuning system]] defines the set of discrete pitches used ~~to tune~~ an [[instrument]] in ~~a composition~~. A scale can be built by taking a subset of pitches from a given tuning system.

	In practice, considering that there are physical limitations to the accuracy of an instrument's tuning, especially in the context of acoustic instruments, a tolerance should be allowed to avoid labelling as abstract what would otherwise be concrete scales. Similarly, playing out of tune with relation to a given concrete scale would correspond to playing outside of that tolerance. The concept of [[just-noticeable difference]] (JND) may be helpful to determine a reasonable tolerance.

	A '''scale''' is a sequence of [[pitch]]es. Each of these pitches is a '''tone''' (not to be confused with other meanings of the term ''[[tone]]''). Each tone can be identified by its '''degree''', its position in the scale, and is often expressed as the [[interval]] it makes with the ''[[tonic]]'', the first tone of the scale.
