You have probably long wondered how cymbals are made. They are spun from a single metal thread. Mostly by Armenian school children.
Kidding. They are stamped from sheets or forged or cast (sometimes roto cast), then worked on a lathe. Mostly. No more hand hammering. The "tone grooves" are remnants of the lathe, not from spinning individual wires.
Most drummers, especially loud drummers, prefer the sheet-made ones, and orchestras commonly prefer cast. The sound is a bit different, and is purely a matter of taste.
Sabian (brand) cymbals are made in Canada. Along with maple syrup and most of the world's snow.
You have probably long-wondered how huge gongs are made...
