1 and a 2 and a...you know this..
Yes and no.I get you now. But the back beat is on three so I wouldn't classify the specific Rosanna beat as a 16th note shuffle. It is definitely a half time shuffle.
..With all due respect....I hope I'm not being an a-hole here...The backbeat is always on 2 and 4. When it's not counted in the accepted manner, yes, the backbeat does appear to be on beat 4, but in reality, it's actually beat 2. One of the accepted ways to count triplets is... one-trip-let, two-trip-let, three-trip-let, four-trip-let. Not 1 2 3 4 5 6. I did that for quite a long time. It's easier to communicate when everyone is on the same page verbiage-wise..
..If you count Roseanna using the above triplet verbiage you will see that the backbeat lands on beat 2 and 4. All shuffles are in triplet time with the backbeat on 2 and 4...
That's because there is no such thing. When you say "time" in that context, it implies a time signature, to me. Even in a more slang sense, I've never heard it and wouldn't interpret it the way he meant. Maybe 12/8 or 6/8 could be interpreted that way but they're not "triplet time". And if you're playing triplets in 4/4 (or any other time signature) then you're playing triplets and perhaps playing in a triplet feel but the "time" is still 4/4.And, regarding using the same verbiage, i spoke and heard quite a few drummers in my life, but i never ever heard someone speak the words that shuffles are "in triplet time"..
