This is by no means a complete list, nor was it intended to be. It should be an improvement over the older videos, as there are now more than double the instruments featured. I chose to include two examples for each type which took an eternity to find and verify them all (or at least the majority). The old videos are now hidden, as this is meant to replace it. For those who want: here are the old links:
