What's the difference between 3/4 and 6/8?

I was flipping through one of my jazz books and saw that when they listed time signatures, they listed 3/4 and 6/8. I don't get it. Wouldn't they essentially represent the same time signature? We don't list things in 8/8 time. (As far as I know, anyway...)
 
Well, the difference is this: 3/4 time is 3 beats per bar, quarter note gets a beat, and the divisions of the beat (eight notes) are two even 8ths per beat. 6/8 time is actually 2 beats per bar, {b]dotted[/b] eight gets a beat, so that each beat is divided into 3 eight notes.

To put it another way:

3/4 time: 1 & 2 & 3 &

6/8 time: 1 & a 2 & a


And if you're one of those people who likes to know the proper names for things. 3/4 time is "simple triple with the quarter note unit of beat" and 6/8 time is "compound duple with the dotted quarter note unit of beat".

Hope that was clear.
 
They're very different feels - 6/8 is used in Latin or African music, whereas a typical 3/4 is a waltz; although in Jazz, 3/4 is more subtle and can often have a two feel as the bass player or just one note per bar.

Personally, I can only "grasp" the difference by thinking of concrete examples - so I would contrast a tune like Afro Blue in 6/8 with say : Freddie Hubbard's "Up Jumped Spring" in 3/4.

Pop/Rock music very rarely ventures into 3/4 and even more rarely 6/8.
 
many times this applies, but sometimes 6/8 is just that - 6 8th notes per bar, depending on where the accents fall, the composer's desired pulse for the piece, or even just depending on the part, it just might make more sense writing it out as 6/8 than it would as 3/4.

i've seen 8/8 and 4/8 listed before as time sigs, mainly in pieces where the sig changes and from some other x/8 sig, to keep the reading consistent.

to me, x/8 sigs imply a different kind of pulse than x/4 sigs do. when i put something together and expect a faster pulse, i use x/8 sigs and if i want a quarter note pulse, i use x/4.

remember the sigs are there just like all the other information on the sheet music, just to help the performer more easily understand the composer's wishes.
 
i always treat x/8 sigs like x/4 sigs, only faster, when i am counting them.

in my band, we do a lot of stuff with odd time sigs, lots of 7/8 or 7/4 along with a lot of stuff that alternates 7/8 9/8 or 3/4 5/4 every other measure, where the drummer might end up playing in straight 4 over it. or not. we also do stuff in 12/8 that ends up being sorta like what pacman was saying, where it really ends up being like a 4/4 waltz - where a dotted quarter gets the beat (imagine a guy on a tuba playing OOM-pa-pa-OOM-pa-pa-OOM-pa-pa-OOM-pa-pa ;) ), only with a triplet pulse.

we also do stuff that's "long" measures, like 13/8 and 15/8 - sometimes this is alternating combinations of shorter time sigs (6/8-7/8 or 7/8-8/8) and other times it's just straight 8ths, like the 13/8 near the end of our instrumental.

for all this stuff i just count every beat, using "sev" for seven, since the accents in our x/8 measures don't always correspond to where quarter notes would fall.

the link in my sig is to our instrumental and it has a lot of odd time sigs in it, as well as the alternating sigs that i was talking about.

I've been struggling with those time signatures also. So how would you count the time per measure? Is it like what Pacman said?

It depends on the application.

TECHNICALLY 6/8 means one beat per eighth note, six per measure. So you would count 1, 2, 3, 4, 5, 6.

I used to play in a band that did Celtic music; 6/8 is used for jigs (reels are in 4/4). The pulse however was a two-beat which gives the FEEL of triplets over cut time (2/4). While I would play bass lines that felt like quarter notes, technically they were dotted eighths.

For jazz, I've seen 6/8 used to notate pieces actually in 2/4 (and 12/8 for pieces in 4/4). This was done to more clearly notate the triplet feel inherent in swing rhythms.

A few examples may help to better understand:

Some examples of triple meter would be the U.S. National Anthem, Amazing Grace, Happy Birthday. One strong beat and two weaker beats.

Some examples of sextuple meter would be Silent Night, Greensleeves, Scarborough Fair. As Pacman pointed out, the main accents fall on the one and four.

I thought it was the other way around.

The only songs on the radio that Ive heard that are in 3/4 is Breaking the Girl by the Red Hot Chili Peppers and some De Angelo song.

A whole lot of Marilyn Manson songs are in 6/8, a perfect circle song or two, longview by greenday, and a whole bunch of other songs which I dont know the names of. 4/4 is by far most popular, but I think 6/8 follows behind in 2nd.
 
I like Pacman's description...a lot.
His sketching the rhythms out makes it easy to SEE how 6/8 & 4/4 relate-
/1 & a 2 & a/3 & a 4 & a/

The 6/8 component-
1&a2&a=123456; 3&a4&a=123456

The 4/4 component(spread over TWO bars)is the boldfaced 1-2-3-4
...which just so happens to be the pulse on the 6/8 component.
Cool stuff(IMO)...is it in 4 or 6?


I was in the gym earlier & the Classic Rock station is on ..."Living In The Past" by Tull was playin', a Pop/Rock tune in 5. Kinda weird...
There are some Pop/Rock/R&B "ballad"-type tunes in 6/8; "If You Don't Know Me By Now"(Harold Melvin & The Blue Notes; also covered by Simply Red)is one I used to play. Same, too, for most of "God Bless The Child" by Blood, Sweat, & Tears.
Chicago's "Colour My World" is in 6; another of their tunes, "Loneliness Is Just A Word" is in 3 & Cetera does some nice walkin'/swingin' in 3. Cool tune.

Fleabass-
"Longview" by Green Day? That's 4-on-the-floor...right?

...and Turner, you're giving me a headache! ;)
 
Big time bump here.

I'm a drummer. I always think of 6/8 as a rocking 3/4. Meaning, it rocks back and forth like 1-2-3, 1-2-3... Listen to All Blues and you'll know what I mean. 6/8 is like two sets of 3/4 teetering back and forth together.

That probably made no sense when you read it, but when you're playing, it's a good way to remember the beat.
 
Actually I think there are plenty of pop songs in 6/8. For example those 50s doo-wop (think Oh Darling! by The Beatles, it's very much in that style), as well as things like Unchained Melody. Then there's things like Michael Jackson's "The Way You Make Me Feel", which could be said to be in compound time.
