[F.] 1. The basic harmonic units in Western tonal music are built by stacking thirds. Piano example: C–E–G.
Bartok, however, is just as at home with harmonic units that include major and minor seconds. Piano example: C–A and F–C–G–D–A–E.
Bartok perceives such harmonies as perfect consonances.
m2 is more dissonant than M2. This Reddit post altercates the math. Thus I'll focus on m2 henceforward.
To me, m2 is definitely NOT "a perfect consonance". But as Dr. Greenberg teaches, it is to Hungarians. Why?
How can I learn, or habituate myself, to hear m2 as "a perfect consonance"?
