Perplex City - We Love Puzzles

I'm working on copying it into Sibelius - i'll upload a midi file to my webspace for those who want a listen.

Plus, reading music wouldn't help too much. It's a snare drum rythmn, so its a beat. I'm assuming we have to work out what piece it's from - but i've got no clue where the title of the card comes into it..

At first I thought it was morse code, but rather than having two note lengths for dot/dash, it seems to have at least three.

I'm vaguely familiar with musical notation but not with drum notation. I found out that it's standard 4/4 time and those quavers with a double bar through them indicate a drum roll (and not a demi-semi quaver like I first thought).

I'm not a drummer so excuse me if this sounds stupid but how do you play a minim with a snare drum without making it a drum roll?

A minim without a roll sounds the same length as a crotchet. So, if you have a 4/4 bar with a crotchet, followed by a crotchet rest, and then another crotchet and another crotchet rest, that would sound exactly the same as a bar with two minims in it.

A cadence is a point in music where chords form a sound like a musical comma or full-stop, to put it like my music teacher would! The the ones that sound like full stops are perfect and plagal (plagal sounds kinda like the amen in church music and a perfect cadence sounds like the piece should end) and the comma sounding cadences are imperfect (sounds just like your voice when you "read" a comma, kinda like a tuneful pause) and interrupted (they sound out of the blue, literally interrupting the music). I don't know if that helps as it's a rhythm rather than a melody but never mind. I'm stumped.

Oh and also, a meter is another word for a tempo, i think. It tends to be used more on music tech software.

Could this be some kind of musical morse code

If 600 meter refers to the tempo, then would this be an extremely quick rhythm?

Does anyone know any famous musical pieces that involve prominent snare drumming? I thought of Bolero, but this is quite slow and was rejected anyway ... any ideas?
