antiphonal

The war was not the only cause of the necessity of Mademoiselle Simone's opposition to antiphonal Gregorian singing.

And spontaneously there rose an antiphonal pantun, or song of war.

The wolves in the valley near-by howled ceaseless responses in this remarkable antiphonal chorus.

It rumbles like thunder, falling and rising as it rolls onwards; it is antiphonal, but changes as it travels nearer.

It is, however, in most cases very difficult to know whether the hymn is actually antiphonal or not.
