All time signatures are created out of groups of 2s or 3s, quarter notes (groups of 2 8th notes) or dotted quarter notes (groups of 3 8th notes).
Any time signature with a 4 on the bottom - 3/4, 4/4, 5/4 etc. - is just that many groups of 2: 3/4 is three groups of 2, 4/4 is four groups of 2, 5/4 is five groups of 2, and so on.
Any non-prime time signature with an 8 on the bottom is made of groups of three: 6/8 is two groups of 3, 9/8 is three groups of 3, 12/8 is four groups of 3, and so on.
Any prime number with an 8 on the bottom is made using combinations: 5/8 is one 3 and one 2, 7/8 is one 3 and two 2s.
In your example, 17/8 is five 3s and a 2: || 12312312312312312 :||
When talking about "compound" meters (meters where each beat is divided by 3), it's probably best to avoid using "non-prime" as the determining factor...simply because it isn't consistently correct. Just off the top of my head, 4 is a "non-prime" number, and yet 4/8 certainly isn't compound time. A better way to identify compound time would be that the top number is divisible by 3 but isn't actually 3 itself.Any non-prime time signature with an 8 on the bottom is made of groups of three: 6/8 is two groups of 3, 9/8 is three groups of 3, 12/8 is four groups of 3, and so on.

wouldn't it be easier to count 17/8 as four 4 and a 1 ?
George,
I think you might be best served by signing up for drum lessons with a reputable teacher and systematically going through the process of learning the instrument.
At the moment, you seem to be continually asking random questions as they occur to you...but in many cases, the questions themselves are not really the types of questions that will move you forward. They're often indicative of underlying misconceptions that you have already adopted. In some cases (such as with the question about "swinging a triplet"), the questions you ask are similar to Zen Koans. In other words, they're kinda like brain teasers that don't have a logical answer.
It's interesting to watch the forum members, especially some of the other teachers like Jonathan and Todd, attempt to answer your questions in the most rational way possible...but I'm not convinced that any of it will get you closer to understanding music theory or playing the drums well.
Just like any of us here on the forum, you're free to ask whatever you like. At the same time, though, I would urge you to simplify things for yourself by considering lessons and a methodical learning process...perhaps with Jonathan or Todd.
It works on this specific case (this song from Billy Cobham) because the tune is built OVER this specific rhythmic concept (7/8 +3/16), wich was very much in use in the 70´s (Mahavishnu Orchestra, Eleventh House, etc.) but it will not work for every case... Same goes for other kinds of countings you need to know the framework of the melody, harmony, etc. to build a coherent rhythm... and a counting (if you need to count) that does not goes against THE FLOW of the musicBilly Cobham has a good example.
Song in 17/16. I count it 1234567..123.....the last 123 is 16ths counted at double speed.
Seven.. 1/8 notes followed by 3... 1/16th notes=17 sixteenth notes
The accents in the music will help you find where to start the sub-count.
Here's Billy.
I tend to give the example of Solsbury Hill (7/4) because it's easy to follow the quarter notes with the bassdrum. I hear the intro as 123-1234, whereas when the verse starts, I hear 1234-123. And the rest of the song keeps switching between the two ways of counting. Nothing in the basic groove actually changes, it's only the basic two riffs over it that change.It works on this specific case (this song from Billy Cobham) because the tune is built OVER this specific rhythmic concept (7/8 +3/16), wich was very much in use in the 70´s (Mahavishnu Orchestra, Eleventh House, etc.) but it will not work for every case...

It is completely acceptable to break longer meters into smaller subdivisions for counting purposes. Thus the comments regarding breaking the meter into groups of 2's and 3's.wouldn't it be easier to count 17/8 as four 4 and a 1 ?

I thought maybe he meant count 4/4 to the 16th note then add one. Edit: ignore this.That would equate to 5, and so I'm not sure how that would be an easier way to get to 17. Besides, 4 would be reduced to two groups of 2, as analysis is concerned with fundamental principles.
That would produce 17/16, not 17/8.I thought maybe he meant count 4/4 to the 16th note then add one.
