Hypolydian mode

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.
