Quadreble

He starts out by saying that there are three sights, the mene, treble, and quadreble, but actually he discusses only two, the treble and quadreble, both of which are read at the transposition of an octave.

The voices include a counter (always below the tenor), a countertenor (moving above and below the tenor), mene, treble, and quadreble.

The counter involves transposition of the sighted note to the fifth below (for extremely low notes a twelfth), the mene and countertenor do not transpose, the treble transposes to the octave above, and the quadreble to the twelfth above.

Not so: for if you observe it, you are to double, treble, or quadreble the length or breadth, as you have occasion.

There is going to be a tremendous rush into Mexico when normal conditions are restored, which must be soon, and now is the logical time to buy land there before it doubles, trebles or quadrebles in price, as it is bound to do.

I would estimate that these modest improvements, which cost lest than £20 in total, have quadrebled how good the guitar is.
