RBT Translation:

The Silent Half Interval

And when he opened the Seventh Signet-Seal, she became a silent one within the Heavenly one, just as a half time interval.

The Mega Trumpet

and the half interval of herself...

The term ἡμιόριον (hēmiorion), derived from ἡμι- ("half") and ὥρα/ὄριον ("time period" or "boundary/interval"), refers to "half a unit of time" or "a partial interval." In the prophetic and eschatological contexts, it symbolizes a shorter duration within a larger temporal framework, such as the "time, times, and half a time" found in the apocalyptic literature (e.g., Daniel 7:25; Revelation 12:14).

Her Song.

vs. the "whole note":

LITV Translation:
And when He opened the seventh seal, a silence occurred in Heaven, about a half hour.

ESV Translation:
When the Lamb opened the seventh seal, there was silence in heaven for about half an hour.
