I was wondering, “how can I easily measure my peak picking speed?” It turns out to be extremely easy, and here is the trick (that I have likely rediscovered):
- Turn the metronome on your iPhone (or somewhere else) to 60bpm, with a loud click that will be heard in your recording.
- Set the camera to record in slow motion, and hold it in your left hand near the pick
- Using your right hand, pick as fast as you can, etc.
- Turn off the camera and the metronome.
Then, when you review the video footage, you’ll hear the metronome click (in slow motion), and you can easily count the number of notes until the next click. I guess hitting 13 or more is what one would want in terms of “make the hand rapidly flip back-and-forth.”
