I need a tambourine. But there are so many kinds. And they apparently don't all sound the same, surprise. I'm not about to pay much for a little tambourine, of course, but I have a few questions: 1. Heads: what do they do? Amplify the sound, I assume? And you can drum on them? 2. Size: if it's bigger is it just louder? Or deeper? 3. Brands: have you used any that you're especially proud of? 4. Cost: what's a reasonable price to pay for a consumer-level tambourine (if there is any other level)? Bye bye.
