While we are on the topic of sound, it is interesting to note that the Grand Gallery seems to be tunable, via it's stepped ceiling construction to four octaves.
The antechamber before the Kings chamber with it's portcullis grooves and granite leaf, is reminiscent of a giant reed, for tuning the cavity.

In musical terms:

The Kings Chamber resonates at 740Hz

= F sharp

The Coffer resonates at 440Hz

= A

In music, pitch is the perception of the frequency of a note. For example, the A above middle C is nowadays set at 440 Hz (often written as "A = 440 Hz", and known as concert pitch). Pitch is often cited as one of the fundamental aspects of music.
