  2. Choose the note range. If you are a beginner, you can focus on the intervals that fall within the first four frets. Or, go for it, and specify the entire range of the guitar.
  3. If you want to raise the bar even more, choose how many key signatures you want the game to fire at you. Choose from 0 to 7 sharps and/or flats.
  4. If you want to go easy on yourself, you can choose only certain intervals to be tested on.
  5. Turn on Require Quality to kick it up a notch.
  6. Turn on Compound Mode and try not to lose all hope.
  7. Choose the level of difficulty from Level 1—no accidentals, to Level 5—"Accidentals of Doom". Now you will really start sweating and your heartrate will skyrocket.

CAUTION: If you choose the full note range, all 15 key signatures, all 25 interval qualities to be tested on, Require Quality on, Compound Mode on, and Level 5—Accidentals of Doom, you are on your own. is not responsible for any brain injury or long-term side effects that may result.
