So, a time signature wherein (a) the pulse subdivides into two portions, and (b) two
pulses are grouped together is called
Simple Duple
. Three pulses grouped together,
Simple Triple
and so forth. A time signature wherein (a) the pulse subdivides into
three portions, and (b) two pulses are grouped together is called
Compound Duple
,
three pulses,
Compound Triple
, and so forth.

Time Signatures and Labels
Simple Meter
Let us address simple meter first. Analyze this by answering two questions
concerning the stated time signature:
1.
For the top number: “
How many…?
” In other words, how many
prevailing background pulse values (or their relative equivalent
values and/or rests) are grouped together?
2.
For the bottom number: “
…of what kind?
” In other words, what
durational value has been assigned to represent the prevailing
background pulse?
So the time signature
2
4
has two quarter-notes grouped together, therefore, we label
this as Simple Duple.

Typical Simple Meters
In Renaissance music, specialized symbols were employed that were the forerunner
of time signatures. These symbols determined how relative durational values were
held in proportion to one another. We continue to employ two holdovers from this
system.
