I'm still pretty new to the forum so forgive me for dragging up a thread as old as this one is . Thanks, "guest" for bringing it to my attention.
Anyway, long before I started playing drums, one of my hobbies was listening to shortwave radio. One of the very first stations I picked up (I was about 6 I guess) was a station called WWV
. For those that don't know it, WWV is a station run by the US Government and it broadcasts one thing all day every day: the time. That sounds boring and to some degree, it is, but at the same "time" (no pun intended) it was and is a very useful station because the clock that WWV gets its time base from is the most accurate clock in the world. I used to keep all the clocks in the house- as well as my watch- to within 1 second or less of the time as announced by WWV.
Now to the topic of falling asleep to something akin to a metronome:
I used to plug in my headphones and turn WWV on just loud enough to faintly hear the second ticks (not wearing them, just sitting near the bed) as I slept. I did this for years (yeah, I know... I'm weird). The upshot of all this is that to this day, I can look at a clock once in the morning and "feel" the time to within 5 or 10 minutes all day without wearing a watch. I used to be called the walking clock because someone would come up to us and ask if anyone had the time and I'd just say "it's about 25 after" without looking at anything. They'd walk off with a skeptical look on their face and ask someone else who had a watch and I'd hear the watch owner say, "It's 9:26..." After a short while, no one doubted my ability to tell time without a watch. I guess I "programmed" myself to feel the flow of seconds, minutes and hours with all those years of listening to WWV in my sleep.
And no, it didn't affect my playing. I don't play exclusively at 60 BPM...
