New SmartMusic needs two sight singing modes: Practice and Testing.
Practice Mode: Teacher can set the number of allowable repetitions. For example, a maximum of 3 takes. After the 3rd attempt, if the student has not already submitted an attempt, then the program automatically submits the best take.
I recommend 3, 5, and unlimited.
Practice mode would allow students to view the visual feedback, locate errors, and [hopefully] strategize how to fix the errors.
Testing Mode: one take followed by automatic submission.
