really really deep sounds can resonate at your heart's frequency and make you have a heart attack,
but everyone knows that....

Actually, intense pulses of low-frequency, high-energy sound can cause pneumothorax. As in your lung will collapse.


However, you're going to need to be standing right next to several large speakers at a concert or have a 1,000 watt "bass box" in your car for it to happen.



Otherwise....everything else in this thread is B.S.

Although, scientists are still checking the Jim Colyer possiblity.

just test it yourself:

But I think he means this:

the devil's chord or the tritone.

Which he?

the starter of this thread?

No one today knows the origin of the term diabolus in musica.

Re: the article that Gooze posted:

All Western Music from before Bach to today relies "heavily on tritones". The Dominant 7 chord, which is the basis of Western tonality contains a tritone between the third and seventh.

Bob Ezrin needs to shut the hell up. There's a reason why he's a "rock producer".


There is nothing in music history that backs this up. The term diabolus in musica is referenced in some musicological works.

My guess:

Some early church composer was probably trying to write a piece in the Lydian mode and the tritone kept popping up and screwing with his voice leading. He then felt the urge to shout out "The Devil's Interval! The Devil's Interval!" out of frustration.

Because of the old way of thinking (normality of sonorities), it was thought of as a disturbing occurrence. Musicians have since learned how to use it effectively.

There are more "dissonant" sonorities then a tritone anyway.

The article made a serious mistake about what "false music" is. Really idiotic.

Considering that the tritone has basically run rampant in metal for years and yearws, and I have never sacrificed goats, I can't give much credence to that odd fear, although it sounds a little more sinister in its minor modes. As for Lydian Mode, I always considered that to be something of a "super major" mode.

Tritone relation is in bold. Half tone occurrences are marked (*):

The F B-natural (tritone) relation in such a conspicuous place makes it a tricky mode to compose in.

They often flatted the B, making it, in practice, not much different than the Ionian mode.
