The Curious Nature of Drummers’ Brains

February 18, 2013

  In a 2011 article in the New Yorker Burkhard Bilger wrote about neuroscientist David Eagleman and his research into time and the brain especially drummers’ brains.

Eagleman New Yorker

Some of the drummers he has interviewed and/or tested include William Champion of Cold Play, Brian Eno of Roxy Music and Larry Mullen, Jnr of U2.

Roxy Music with Brian Eno

Eno, on keyboards (above) who was working on a U2 album,  talks about Mullen’s amazing timing.  They were using a click-track (computer generated beat) when mMullen complained he couldn’t drum to it. ENO adjusted the beat. Mullen was happy.

larry Mullen

ENO adjusted the beat by 6 milliseconds!!!!!!!!!

6 thousandths of a second.

Cool Larry Mullen Jnr Drum solo

Tempo is measured in beats per minute or bpm. 

Drum Beats for different tracks:

Drum Beats

Here are some drum beats provided by Justin Alan Cox so you can get your timing right:

60 bpm

80 bpm

100 bpm

120 bpm

Drummer Maths:

How Cool a Drummer are you?

Pick a beat and see how accurate you can beat tempo. Time how long it takes you to beat out 60, 80, 100 or 120 drum beats using a pencil.  It should, obviously, take one minute if you are an ENO or a Mullens.

What was the difference in time in seconds?

Calculate your % error = time error (sec)/(60 sec) x 100

Bilger’s conclusion:

‘Like perfect pitch, which dooms the possessor to hear every false note and flat car horn, perfect timing may just make a drummer more sensitive to the world’s arrhythmias and repeated patterns, Eagleman said—to the flicker of computer screens and fluorescent lights. Reality, stripped of an extra beat in which the brain orchestrates its signals, isn’t necessarily a livelier place. It’s just filled with badly dubbed television shows.’

Headbanger Maths

February 18, 2013

The NHS reports that Australian Researchers Declan Patton and Andrew McIntosh, Uni of NSW, have conducted a study into brain and neck injuries of headbangers published in British Medical Journal.

Concerts included as part of the study included Motörhead, Mötley Crüe, Skid Row, The Hell City Glamours, L.A. Guns, Ozzy Osbourne, Winger, Ratt, Whitesnake and W.A.S.P.

Here’s Motorhead with a ‘nice’ moshpit.

motorhead

…………………………………………………………………..

The Headbanger Study Concluded:

1. Head movement of more than 75o for an average heavy metal beat will cause head and neck injuries. This movement causes headache and dizziness.


mosh pit boy

 2. Beats above 130 bpm (beats per minute) cause neck injury.

The average headbanging song has a tempo of about 146 beats per minute (bpm).

and according to Mathspig:

3. Being punched up in the mosh pit. Do you need maths for that conclusion?

Researchers recommendations:

1. Reduce range of head and neck movement

2. Headbang to a  slower tempo

3. Wear a neck brace. (Isn’t a bad hair cut enough?)

Headbanger Rates Exercise:

How many headbeats per hour would a headbanger manage for the following song tempos. Here are just a few tempos form Play Drums Now blog:

Song Tempos

Mathspigs excited .Look there is a band called Mutemath!!!!!!!! And here they are:

Maths the Musical

February 18, 2013

Here is the challenge Mathspiggies.

……………………………………………………………………………………..

Can your math class make a musical maths video. Some of these are awesome. Firstly, if middle school math students see senior maths students having fun they will want to do it. This is called PR.

……………………………………………………………………

And, secondly, it seems that the countries with the best global school maths results are also the countries doing maths musicals. Think about that!

Here is the band called AMERICA AFTER MATH. It is in the genre known as Math Rock (More to do with the beat):

America After Math   US Math Rock Band

Math Rock Challenge:

There are lots of rock groups with maths-linked names. So make up a Mathsy Group name like

Pythagoras and the sum of the squares

and go for it. Make a video. Make maths fun. Here are some inspiring you tube clips.

The Great Maths Scavenger Hunt: The Rules

August 15, 2012

The Great Maths Scavenger Hunt

THE RULES

………………………………………………………………………………………………………………

Teacher Notes

Aim:

To have fun with maths.

To use lots of different skills

eg. artistic, photographic, performance, comic involving maths

To have something in the challenge for every member of the class not just maths whiz kids.

Timing:

Week 1

Introduction: Form teams in class time. Give them the Scavenger Hunt Sheets so they can devise their team name and war cry/anthem.

eg. QTπ, The Smart Asymptotes,The Quadratics,The Nerd Herd,Numerators, Number Nutters and The Vulgar FactionGive teams 1 week to gather or create scavenger items.

You will find a complete PDF file of The Great Maths Scavenger Hunt @ the end of the following post, plus a PDF file answer guide.

Week 2:

Students are to bring items to class.

All teams must perform their war cry/anthem. Other performance items should be presented.

Score:

Any calculations must be written down. All graphs should be hand drawn.

Teams should then tally their own scores.

Cross check with another team.

Prize:

The prize will be a dodgy trophy (see pic) that you buy at a Op shop/ secondhand shop.

Rebrand it.

Decorate with hideous ribbons.

And make a fuss. This is Parody Power and everyone is in on the joke.

The trophy should be awarded with great fanfare.

Perhaps, you could include a fanfare like this.

4. Keyword Rap

August 3, 2011

.

.

.

.

This is the Hey! Ho! Moment.

You write down the keyword lyrics first and riff. You don’t have to be good. 

But you must never smile. It is a rule. Rappers don’t smile. They are some of the most miserable millionaires on earth.See Eminem and 50 Cent below.

.

.

.

.

.

.

.

.

.

Here is an example playing with Square Roots.

eg.

Whatcha gotta know ..

Whatcha gotta know 

surds .. absurd .. surds …

√2 you do.

√3 happy

√4 Want more?

√5 Ha! Ha! Ha! Staying alive. ( A little Bee Gee Riff there.)

Chorus: Hey! Ho!

Whatcha gotta know ..

Whatcha gotta know 

surds .. absurd .. surds …

√6 clickety clicks.

√7 Go to heaven.

√8 Don’t be late.

√9 Divine.

Chorus: Hey! Ho!

The trick is to get the kids to stand together and swing their hands up in the air and across chanting HEY! HO! for the chorus.

If you want to see rapping it is done Google: True Live. Keep Myself Awake

Some kid may take pity on you and do the Keyword Rap with beat box sound effects for you.

Watch this video clip. Get inspired. Then get outside. Start something.

This is a  You Tube clip of MTN Clap shot in Hillbrow Sth Africa.

Here are some lyrics from the MTN Clap shoot:

Three, six, nine

The goose drank wine

The monkey chewed tobacco

On the streetcar line

The line broke

The monkey got choked

And they all went to Heaven

In a little row boat

Clap, pat, clap, pat

Clap, pat, clap, slap

Clap, pat, clap your hand

Now the trick is to convert this to maths.

NB: √4 = Root 4.

Naught, 1,2

The goose drank glue

The monkey did some square roots

√4 it equals 2

1,2,3

The goose drank pee

The monkey said the goose is mad

√9 it equals 3

2,3,4

The goose drank more

The monkey said the honk would conk

√16 it is 4

3,4,5

The goose stayed alive

The monkey scratched his armpit

√25 is 5

4,5,6

The goose drank bricks

The monkey said the goose is gone

√36 is 6

5,6,7

In goose heaven

The monkey said I miss the goose

√49 is 7

6,7,8

The goose can’t wait

The monkey heard a goose ghost ‘hic’

√64 is 8

7,8,9

The goose drank wine

The monkey howled ‘Not again!’

√ 81 is 9

8,9,10

Drunk goose again

The monkey chased the hic-ing honk

√100 is 10
