I wonder if there’s a name for the famous rhythm heard many times around the web. I’d like to know its origins but I can’t google it without a name. I wrote it down but I can’t describe anyway differently, so here it is: The rhythm is one of this three (those signs are just quarter pauses: sorry for the bad handwriting) It should be one of the three here, where those mysterious signs are just pauses (sorry for the bad handwrite).
Than to everybody.

Edit: I’m now thinking that probably the last note is doubled and the last pause isn’t there.

The "Shave and a haircut — two bits" rhythm...

X: 1
T: Shave and a Haircut – Two Bits
T: Rhythm
K: clef=perc stafflines=1 middle=B
M: 4/4
L: 1/4
B B/2B/2 B B | z B B z |]
w: shave and a hair- cut, two bits!

...goes back at least to Charles Hale in 1899 according to Where does this famous rhythm pattern come from (oftenly used to knock on a door)?, which references Wikipedia: Shave and a Haircut.

The history is well described in the linked MusicFans.SE post; so, this being MusicPerformanceAndTheory.SE...

All three of the notations in the OP are correct; there is no canonical notation, just a set of rhythmic relationships, all of which are expressed. The eighth notes (or sixteenth notes: i.e., "and a") can be played straight or swung.

The traditional/characteristic "melody" is...

X: 1
T: Shave and a Haircut – Two Bits
T: Melody (standard)
K: none
M: 4/4
L: 1/4
c G/2G/2 A G | z B .c z |]
w: shave and a hair- cut, two bits!

...or sometimes...

X: 1
T: Shave and a Haircut – Two Bits
T: Melody (variant)
K: none
M: 4/4
L: 1/4
c G/2G/2 _A G | z B .c z |]
w: shave and a hair- cut, two bits!

...and also...

X: 1
T: Shave and a Haircut – Two Bits
T: Melody (variant 2)
K: none
M: 4/4
L: 1/4
c (3G/2^F/2G/2 _A G | z B .c z |]
w: shave and -a hair- cut, two bits! 

The final rest is sometimes replaced with a "stinger" — an instrumental accent to end a piece.

X: 1
T: Shave and a Haircut – Two Bits
T: With "stinger"
K: none
M: 4/4
L: 1/4
c G/2G/2 A G | z B .c .!>!C |]
w: shave and a hair- cut, two bits!

It's known as "shave and a haircut".

    6 bits (I think) –  May 14 '21 at 23:30

    @ggcg That's a variant — usually 2 bits. – Aaron May 14 '21 at 23:46

    I learned it as 6 bits. Inflation i guess –  May 14 '21 at 23:59

    Roger Rabbit said "two bits", so I reckon that's definitive :-) – Mark Bluemel May 16 '21 at 19:41
  • I remember that I first heard it as "two cents" but "two bits" seems to be most common – ojs May 17 '21 at 09:47
  • Two bob where I come from... – RedSonja May 17 '21 at 11:22

    @ojs More inflation. For those unaware, 2 bits is equal to 25 cents - fun fact: they used to divide the dollar (which was a coin in those days) into 8 bits - this is actually where we get the 8-bits-to-a-byte conversion which is used in computer science to this day. It's also related to the pirate saying "pieces of eight", because they would literally slice coins into 8 pieces. I believe the pound coin was subject to the same treatment in the UK, which might be where "bob" comes from? – Darrel Hoffman May 17 '21 at 13:29

    @DarrelHoffman source please, I highly doubt that. In the early days there also could be 6bits (among other values) in a byte, depending on the hardware. https://en.wikipedia.org/wiki/Byte – Swedgin May 17 '21 at 15:27

    @DarrelHoffman 'Claude E. Shannon first used the word "bit" in his seminal 1948 paper "A Mathematical Theory of Communication".[7][8][9] He attributed its origin to John W. Tukey, who had written a Bell Labs memo on 9 January 1947 in which he contracted "binary information digit" to simply "bit".'

  • @Swedgin Alright, I stand correct on computing bits - the rest is pretty much true though. It actually comes from the Spanish dollar originally, which predates US or UK usage. Just a coincidence that computers also later settled on 8-bit groupings as the de facto standard. Though for similar reasons - you can easily divide something in half (whether a coin, a chunk of computer data, or for that matter a musical beat or a scale) 3 times to get 8, so powers of 2 resulted in the same value in multiple instances. – Darrel Hoffman May 17 '21 at 15:51
  • @DarrelHoffman there were 20 bob in a pound. I'm fairly sure nobody was cutting pounds into 20 pieces -- it's not particularly easy to divide a circle, half circle, or quarter circle into five pieces. Wikipedia says that the origin of the term is uncertain but there is speculation that it derives from the name of Robert Walpole. – phoog Jan 09 '24 at 10:47
