A concrete tuning system defines exact intervals between all of its possible notes. Examples include untempered just intonation and equal tunings. An abstract tuning system has at least one variable interval, often constrained to preserve certain important properties. In other words, an abstract system is a set of concrete systems that have some characteristics or follow some rules. Depending on the characteristics or rules being considered, a concrete tuning system may be part of multiple abstract tuning systems. The most notable class of abstract systems is the regular temperaments. | ||
