Lets say you want to learn Pentatonic minor scale. First you will need to learn all 5 of its pattern shapes in the key of "a". When you are already familiar with these pattern shapes, and you can play them on your guitar, go to: Settings tab / Scale Names and select Pentatonic minor only. In Settings tab / Keys make sure all keys are selected. Now, go to the Practice tab and press the random generator button. It will generate a pentatonic minor scale in a random key and pattern for you, e.g.: g Pentatonic minor - 3rd pattern. Practice the scale pattern on your guitar for a min. of 20 minutes, and maximum 1 hour. Next day go to the Practice tab again and generate a new scale pattern for yourself, e.g.: c Pentatonic minor - 4th pattern. Continue like this every day, for about a month. After one month of practicing, you will gain a good knowledge of the Pentatonic minor scale in all keys, and you will feel comfortable with it on your guitar's fretboard. If you are already familiar with couple of scales and all their patterns, e.g.: Pentatonic minor, Pentatonic Major, Blues or Major (Ionian), select all these scales in the Settings tab and use the random generator in the Practice tab to generate a random scale with random key and pattern to practice any patterns from among these scales. Naturally, you can create any combination of scales and keys for practice.
