Here's an example: http://www.soundslice.com/tabs/2865/adrian-holovaty-everythi...
Now they've launched a sheet-music player that's featured on the homepage. Adrian has posted an article about it on his blog: http://www.holovaty.com/writing/soundslice-sheet-music/
Currently, only they transcribe the sheet-music, via their Pitch Perfect program: http://www.soundslice.com/pitch-perfect/
I would love to practice guitar with something like this. Hopefully they start to offer more songs.
That's my hope as well. It's good to see someone attempting to compete with ultimate guitar, which lets be honest, hasn't done a damn thing to improve their site in the last 10 years.
I won't lie, I've totally stagnated in playing because most learning resources are awful.
Aren't there any services out there for sharing of music played alongside the sheet, just like they do in the example, mostly for classical music?
