I recently started playing with a bachi, and I’ve been having some mixed results with it. I have no trouble at all with doing just a regular downstroke (maebachi?), but when I do an upstroke (ushirobachi?) the bachi catches on the string and twists in my hand.
Any idea what I’m doing wrong? I feel like I might not be gripping hard enough, because I use a fairly relaxed grip.
