I think part of the initial difficulty is overcome just as you "learn the song" and recognise where the dings are supposed to fit into the music.

Also the correct timing for 'critical hits' seems a little bit later than I expect it to be.


And for people who can't pass it at all - is there any chance you're quitting as soon as the music goes bad, thinking it means you've failed? It'll keep going and you can recover if you hit enough good notes.
