From this point on, the lessons will be organized in a slightly different way.
Moving to the Next Lesson
Similar to the Beat Speed Difference Sensitivity test, you will be required to get a minimum score in all exercises in order to move to the next lesson.
Levels
Also, for each exercise, the tests will now come in different levels, or difficulties. For each exercise, you will be required to tune a note so that its interval's beat speed is within a certain limit. The levels will get harder to tell that limit; the final level requires you to tell just by listening to the unfiltered audio.
Level 1 - You will see the beat speed displayed as a number in bps on the screen or be shown some other graphical representation of the beats, as well as hear the beat completely filtered; it will sound pure and it will be the only thing you hear.
Level 2 - You will not have any visual represntation of the beat. No numeric bps or graph. But you will still hear the beat completely filtered.
Level 3 - You will hear the beat speed partially filtered; some of the other frequencies of the string will be audible.
Level 4 - You will hear the beat speed unfiltered. The Real Deal. (Well, as close as you can get on a computer.)
