Very nice.
I thought this was a good start, but it could use a little refinement. Here are a couple of my notes:
-- I noticed that the forward/continue button just said "Menu." It advanced the slides, but you may want to correct that.
-- Stop music button was nice, but is there a way to restart your ambient music? I tried clicking the button again, but it didn't work.
-- I think it would be very useful to add music being played when notes are displayed on-screen. Individuals tend to learn best when they can associate what they see (notes on display) with a functional outcome (notes being played). For example, you could just have an audio file pluck out the notes to 'Crazy Train' as each tab is highlighted for demonstrative purposes.
-- Something to consider is some type of interactivity at the end of each lesson. Whether it's a tone matching game, or just a blank sheet to make your own tab, I think an add-on of that sort would complete this package.
Those criticisms aside. Solid start to flash/tutorial work. I look forward to seeing more of your work. Congratulations on the Daily Feature.
