Hypolydian mode

from Wikipedia, the free encyclopedia

The hypolydische mode , short Hypolydisch is to Lydian belonging Plagaltonart . In the medieval system of church tones it is also called the sixth tone or tritus plagalis . It differs from the Lydian tone ( tritus authenticus ) in that it has a pitch range ( ambitus ) shifted downwards by a fourth and a different repercussa ; however, the finalis remains the same:

Lydian Hypolydian
Ambitus f – f 1 c-c 1
Repercussa c 1 a
Finalis f f

For today's applications (e.g. in modal jazz ) the hypolydic mode does not play a role, because the modal scales do not differentiate between authentic and plagal . So here there is only the Lydian , but no Hypolydian scale.
