The story tells that Baber--a music writer, create music out of bikes.
BABER: For instance, when you pluck a spoke on a wheel, you're not just hearing one, you're hearing all of them. They all ring out from sympathetic vibration. So the way to solve that was to tune every single spoke to the exact same pitch, which takes forever.
What's the meaning of "take forever" here? Forever to the same pitch after tuning?
