Knobswitch

Each level has a maximum of 10,000 points available to earn. For this trophy, you need to complete any of the 10 levels without making a single mistake (guessing the incorrect interval). It is highly recommended you use a Music Tuner for this trophy as it will make it much, much easier. If you make a mistake, you will have to either try again on a different round or exit back to the main menu and start again.

Once you have completed a level perfectly, you will receive 10,000 points and the trophy will unlock.

You will get this as you go for Perfect Game.
