Greetings Everyone,
This was a great class. I
really enjoyed it and I hope you all got something out of it. It was my
first time teaching it so I was caught a little off guard but I think we
all did quite well especially with the tools we had.
By the way, everyone got this one wrong so here it is:
Cross-rhythm
You have to start with
duple a binary (duple) division of the basic meter (not the pulse) i.e. 2/4
triple an tertiary (triple) division of the meter (not the pulse) 3/4
Additive:
adding a binary and a tertiary together as a linear meter to create an
irregular meter (2 + 3) i.e. 123 123 12 12 12 (two 3's
followed by 3 2's. for a total of 12. Could be written in 12/8)
Now, a Cross-rhythm is when one percussion section is playing in duple, and the other in tripe, at the same time.
They take their cues from a "clave" ( of one kind or another, that's
the Afro-Cuban name for it) that keeps the basic pulse and suggests
where thee threes and the twos can be played on.
So it's not 3 plus 2, it's 3 AGAINST or OVER 2 (or visa versa)
It's
not just two different rhythms played at the same time. That's just
random. It's a very precise and a very sophisticated use of rhythm and
it is characteristic of Sub-Saharan music, especially the sacred possession music.
HAVE A GREAT SUMMER!
