This app will test your ability to recall the 7 Diatonic Modes on the fretboard of the guitar. The challenge is to imitate how the notes are played for each mode on the fretboard. For each mode, you will be given 3 patterns to imitate. For the first two patterns, you will be asked to perform the modes ascending, and then ascending and descending. On the 3rd scene of each mode, you will be prompted to perform the mode with an interval pattern. Each mode has a different interval sequence for the 3rd pattern. The numbers on the notes denote which fingers are to be used. The modes are based on the key of G major.
