February 13, 2015

Middle School Maths Challenge

Rates, averages and crazy drummers (That’s all of them, man!)

Here are 3 classic rock songs. Listen to the tracks and find the beat per minute or bpm of each song.

HINT: Count the beats and ask a friend to time you.

# Beat 1: AC/DC …  T.N.T.

………………………………………………………………..

# Beat 2: Queen …  Another one bites the dust

bpm for above clips

………………………………………………………………..

# Beat 3: Uptown Funk …  Mark Ronson

Lyrics may offend some.

Find the Uptown Funk bpm here.

# BIG challenge 1:

Ramon Sampson

Pick one beat and see if you match the exact bpm. If you don’t have drumsticks use pencils.

HINT: Count the beats and ask a friend to time you.

# BIG challenge 2:

Record yourself drumming to your own natural beat for 10 seconds.

Listen to your recording and count the beats. Multiply by 6 and you have your bpm.

Do this 4 times.

Calculate your average bpm.

Then for each of the 4 trials calculate the % error.

Pro drummers do not like to be out by 1 beat or 1 bpm. They want to hit ZERO % error. I beat out per minute for a bpm = 84 would mean an error of approx 1%.
