An '''inflection''' is a microtonal accidental. Using this term allows the term '''accidental''' to refer exclusively to sharps, flats and naturals. Accidentals and inflections are referred to collectively as '''alterations'''. This terminology greatly facilitates discussions of microtonal scores.
Microtonal accidentals are sometimes referred to as '''inflections'''. Using this term allows the term ''accidental'' to refer exclusively to sharps, flats and naturals. Accidentals and inflections may then be referred to collectively as '''alterations'''. This terminology facilitates discussions of microtonal scores, especially in rank-1 and rank-2 systems.
