DJ Hero

Once you open the game and insert it into your Playstation the only thing you will be able to do is the "Learn to DJ: The Basics" tutorial, which consists of 5 easy tutorials:

1.Welcome to DJ Hero
2.Taps
3.Scratches
4.Crossfader
5.Stars 

Once you've completed this you will be asked if you want to do the advanced tutorial, which consists of 6 tutorials which are a little bit harder than the ones you did before. Continue with the next tutorial, "Learn to DJ: Advanced Techniques" which is formed by the following 6 short tutorials:

Learn to DJ: Advanced Techniques
1.Directional scratch
2.Scratch sequences
3.Crossfade spikes
4.Euphoria
5.Rewinds
6.Freestyling

You dont have to complete them correctly but I recommend you do because if you don't know this techniques you wont have chances of getting much of the trophies in this game.
