Thanks again for the advice.
Apply what you are working on by playing allow with pre-recorded music. This will allow you to make the figure or rhythm feel good within a music context and perhaps tear down some of those walls that mess with your brain when it comes to playing over the barline.
I've been planning to identify a collection of songs recorded at different tempo settings (60, 70, 80, etc.) to play along with so I can progress through different songs as I develop speed, instead of just notching up the metronome. This could be a great first project to work through with that approach.
Record myself and listen back to what I'm playing... Isolating the differences will then allow you to attack the exact problem that is making it feel uncomfortable.
The problem is that when I play a roll across the barline, everything before the barline gets "crushed", like a ruff or drag or flam. Feels natural, sounds awful and throws off my timing. Gotta work on that.
Remember, there's nothing physically different going on; it's all in your head and how you are perceiving what you are playing ... in relation to the music, the pulse, and the meter (time signature).
Exactly. It's like my new avatar, where you can see a vase if you look at the "figure", or you can see two faces in profile if you look at the "ground", or background. Some people see one, some the other.
To play across the bars and keep a good strong beat at the same time is a bit like always seeing the vase and the two faces at the same time, or like hearing both parts in a counterpoint piece at the same time. Confusing. There's a natural tendancy to focus on one and lose the other.
Count out loud. Doing this will help internalize the pulse and where you are in the bar/measure.
To my ears, at least, it seems a lot of Jazzers escape this problem by losing the beat entirely, playing all over the bars, and then coming back to the beat. 4/4 time becomes, for a while 1/8 time while they wail away, and then they find the 4/4 pulse and wander back into it. (I think the book Drum Wisdom called that the "1/8 flow" or the "8/8 flow".)
That may be a great approach for improvisational music, but it's not so great for, say, a dance Rock band. It's brilliant, but it doesn't have the same level of commitment to the beat. And as Arethra Franklin once said, Rock & Roll is all about commitment.
I think you're right. I've gotta learn to keep counting while playing across the bars.
Is there a particularly good book of exercises for playing across the bars?
