  • All exercises can be repeated as many times as you'd like up to the due date

  • If you achieve a score lower than 90%, or run out of time before doing 20 problems, the exercise will give you the option to restart
  • Once you complete an exercise, you can return to practice anytime you like, once graded your grade will not change with further attempts.
For this exercise: you will see simple intervals from unisons to octaves. Remember, the only thing to focus on is the size of the interval to determine if it can be placed in the perfect or imperfect category.
  • Perfect intervals are 1, 4, 5, and 8.
  • Imperfect intervals are 2, 3, 6, and 7.
