I was disappointed in the product. This is the first time I have purchased one of the "100 ..." documents and I was expecting a bit more. Just a list of names. I expected a sentance or two to accompany the name to at least give an idea of what the instrument is. Some are obvious just because of its ubiquity, but others I would have to look up to even get an idea if the instrument was wind, stringed, percussion, etc. If I need to look them up, then I don't need the list and can just google for musical instruments.
It is what it advertised - a list of 100 instruments. But just names?!? For this reason, I will probably not purchase any further "100 ..." products.
