Hello List,

I have not contributed much to the list, though I am somewhat passionate about 
the nomenclature used for rhythm in the United States, so:

From my perspective, the best possible description of meter is found within 
Mark's first hyperlink below. It differentiates between two things: how many 
beats there are in a bar and how each beat is subdivided.  The beats in a bar 
are described as either duple or triple (two beats in a bar or three beats in a 
bar, respectively) and simple or compound (two divisions or three divisions 
respectively).  Four beats in a bar is called quadruple, but it is often 
difficult to differentiate between duple and quadruple meters, so most texts 
(and teachers) would accept either duple or quadruple for most meters in which 
the quarter- or half-note is the basic pulse.

Examples: given a bar in cut time, each beat filled with eighth notes 
(quavers), the tag would be simple duple.  Given a bar in 6-8 time, each note 
filled with eighth notes, the tag would be compound duple.  Given a bar in 3-4 
time, filled with eighth notes, the tag would be simple triple.  Given a bar in 
9-8 time, the tag would be compound triple.  If there is no subdivision, then 
the subdivision tag becomes completely unnecessary, but this rarely happens in 
music.

Notice that the subdivision tag is notated BEFORE the time signature tag.

For most University students stateside, this is a bit confusing at first 
because most beginning teachers teach that 6-8 has six beats, whereas with the 
above scheme it has two beats.  In most cases this is true, though in some 
adagio dance movements, the proper count may be six beats to a bar -- in which 
case the tag given is simple triple (each bar receiving TWO iterations of the 
triple beat).  This is all based on the way that the music is HEARD not notated.

For this reason, I would go with duple and triple rather than binary and 
ternary, but this may be based on a difference in nomenclature in the US.

Thanks,

Michael Dougherty

Hi Tom, hi list,

Rhythm and meter (or meter) are two are entirely different beast of course. See:
* http://lilypond.org/doc/v2.12/Documentation/user/music-glossary/meter#meter
* http://lilypond.org/doc/v2.12/Documentation/user/music-glossary/time#time
* http://lilypond.org/doc/v2.12/Documentation/user/music-glossary/rhythm#rhythm

6/8 is a duple time that consists of two ternary beats.

I've posted a request to add some information on this to the Lilypond
glossary to lilypond-bug.

Sincerely,

Mark
