I must be crazy to spend so much money on a "piece of metal" I thought to myself the whole time before the bowl arrive.. But when I finally heard the first notes, there was an amazing experience. Fate (or the hand of the distribution worker) assigned me a bowl playing in the tone of F at about 150 hz, and while singing I get out a hypnotic 62 hz. The reverberation is clean and really very long, the mass is simply recognizable. I was secretly hoping for a D or G tone, but I'm still very satisfied. It's fine that when experimenting with different types of hammers or mallets and stroke energies, I manage to coax out other tones as well, so that's cool too.
