Karaoke Revolution

Without a doubt this is the hardest trophy in the game.

I strongly suggest you run thru career mode first, and follow the guide for "Face the Music" trophy first to get your feet wet.

You need to get the 100% accuracy award while singing on the hardest difficulty setting, Expert.

Pay VERY close attention to the bar on the bottom quarter of the game screen. As bars scroll from right to left, you need to match the pitch precisely, so that each and every bar has a green arrow for the entire song. The way the arrow works is:
> = Perfect pitch, this is what you need
> = Close, you need to marginally shift the pitch to be precise.
> = Off, you need to adjust your pitch somewhat.
> = Way off, you will need to adjust your pitch dramatically.
> = No lyrics, doesn't matter; feel free to test your pitch during the gaps.
If the arrow is anything but green, it will also show the way you need to adjust; if the arrow is below the bar tilted up then you are singing low and need to sing at a higher pitch, while if the arrow is above the bar tilted south then you are singing at a higher pitch and should reduce your pitch to match the note.

Every nanosecond with the bar yellow, orange or red, reduces your %. You will need to have the bar green for 99.6% (or more) of the track's bars to round off to 100%

Each track is obviously very different, and while you have certain songs you prefer, they might not be the best choice for this particular trophy. For this trophy, the better ones have mostly straight pitch/bars. To make sure this is understood, "Just Dance" has the pitch jumping up and down consistently, while "I Melt With You" has most of the song in a straight pitch with only a few tricky parts. While I never sang "I Melt With You" before this game, I strongly suggest it for this trophy. The pattern for this song is rather quick to catch, finding where to shift your pitch slightly up or down for a single word. The trickiest part is matching the bar for the word "Melt" (which you hit twice during the short version of the song). It is still tough as nails, but simpler than any other track for us. (Also note that if you are playing the EU disc, there might be an easier track we don't have.) It takes VETERAN singers over 50 tries to hit 100%, and if you currently aren't able to match the pitch exactly, you will need to bring up your singing skills to expert levels.

Keep practicing the track you are best at in Short mode till you get this. While repeating over and over you will begin to pick up the pattern where you tend to be off, fix that and you will see the difference and it's getting better all the time.

NOTE: When you complete this, you will also for sure unlock all the trophies referencing this. You will also unlock a bunch of other trophies, in addition to racking up many platinum and sensational scores.
