 Though just intonation in its simplest form (5-limit) may seem to suggest a necessarily tonal logic, it need not be the case.Some music of Kraig Grady and Daniel James Wolf uses just intonation scales designed by Erv Wilson explicitly for a consonant form of atonality, and many of Ben Johnston's early works, like the "Sonata for Microtonal Piano" and "String Quartet No.2", use serialism to elide the predominance of a tonal centre.
