They both suck?

I've also heard that refridgerators hum in Bb and that a dial tone is mostly Bb (useful if you dont have a guitar tuner around)

60Hz? Just a teensy bit sharp of Bb.

And considering that DJ Dial-tone is my personal music project... Hmmm.... Hmmm....


B-Flat is the 23 of the music world

isn't it the same thing as c#

Yes it is the same as C#. I've always wondered why people seem to gravitate towards Bb when talking about Chandra and alligators.

No, sharp is a halftone above; flat a halftone below.

Oops...

You mean A#?

A#.

When assigning major scale notes to various keys, two rules are applied:
1. Each letter (A through G) is used only once.
2. Half-tones are either all sharps or all flats.

Applying these two rules results in Bb being used more often than A#.

The sound from black holes is a warning: Stay away from be or you'll be flat.

I prefer C# to C. But then, I never liked pointers.

both can rip your face off with relative ease.

I actually tried the Bflat humming on those stairs...it's such a surreal experience.

Glenway Fripp is a strange and amazing person. He regularly comes into the local coffee shop and plays the piano. We've been at the same dinner parties multiple times and yet he somehow still thinks my name is Beth (it's actually Sara.)

Both Gregorian and Buddhist mantra chants make a lot of use of B flat tones.

Regarding the razor thing, there is a table of note frequencies here: http://www.phy.mtu.edu/~suits/notefreqs.html and we know that US electricity is supplied at 60Hz. This is equidistant from the B-flat at 58.27 and the B at 61.74. So, it makes sense that US electric devices that vibrate at the electrical frequency will make a B-half-flat noise.

As for alligators - it's well known that infrasound affects human moods, although there's no clear conclusion as yet as to which frequencies induce which moods in which people, and the field has mostly been left to crackpots. Infrasound should also affect the moods of alligators. Here's an article about their hearing and vocalizations: http://www.acoustics.org/press/151st/Todd.html

I've not read the linked article, but I'm guessing that the answer is that neither are very good for cleaning your arse.

Yay, Terminal Verbosity! That line has gone through my head for 20+ years.

Oh, and the Raveonettes recorded an entire album in B flat. (I frickin' love "Chain Gang Of Love".) It's sorta White Stripes hit Phil Spector's wall of sound.

C# (c-sharp) is equivalent to Db (d-flat).

A# (a-sharp) is equivalent to Bb (b-flat).

Technically, C is also B# (b-sharp), as F is E# (e-sharp).

Regarding the tonics, A# isn't very practical. A# minor requires 7 sharps, in other words, every note. A# major isn't even classically list-able as a key signature, as it would have 10 sharps, requiring C## (c-double sharp) F##, and G##.

While enharmonically equivalent, Bb major only has 2 flats.

Basically, Bb major is much easier.

Also, as somewhat of a simple generalization, wind instruments "think" flats, and string instruments "think" sharps.

I wonder if B-flat, at some octave below middle C, is the fabled "brown note"? It would make sense, sort of.

9837; + 9839; = 9838; ?

I thought there were some specifics regarding temperament which made an A9839; not exactly the same as B9837;

Most electric razors these days are of the cordless variety, using 50/60Hz electricity from the wall only for recharging their batteries. Their motor then operates on direct current. Consequently, the note they hum can be pretty much anything. My Braun is definitely singing "C", when it's not in a thick stubble.
