Exercises mode


The song, which you have chosen, is the basis of exercises. The purpose of the exercises is to strengthen the memorization of lyrics.

Here you can find the description of the Tutor window.


  • You can choose between four types of exercises. The exercises are arranged in accordance with the increasing of their difficulty. A special algorithm confused the song text (lyrics). The task of each exercise is to restore the lyrics.
  • The sum of points is the estimation of your result, which you receive after having finished an exercise. You can do exercises an unlimited number of times, till you have received the excellent result (in accordance with the sum).
  • Each exercise consists of a set of tasks. These tasks deal with lines, or with words, depending on exercise type. The confused lines or the confused words are tearmed as task objects.
  • You can quit your exercise at any moment and this action saves the current exercise state to return to it later, though you can start this exercise from the beginning. A special algorithm generates new tasks, excluding repetitions.
  • During any exercise, the task objects can be in several states. Song lines have three possible states. Indicators designate those three states. You can find the indicator on the left side of any line. The exercises, which deal with words, distinguish three states of words. The kind of underlining (or absence of any underlining) designates the state of any word.


Exercises Dealing with Lines



Task Descriptions

Repair LineYou have to restore a correct word order in a song line.

Repair Obscure LineYou have to restore a correct word order in a song line, and put into a trash can a wrong word.

Important! It is quite normal to listen to the correct pronunciation of a line by the singer and announcers as many times as you want.

The note: Punctuation marks of a song line are ignored to simplify your task.


Line states in the Repair Line exercises and the Repair Obscure Line exercises can be as follows:

On-start state

You have not begun this task yet, or it has been interrupted.

In-process state

The task is finished, but you have one or more errors.

Finished stateThe task is finished without errors.

Exercises Dealing with Words



Task Descriptions

Repair WordYou have to restore the word in which letters are confused.

Repair Obscure WordYou have to restore the word with confused letters, deleting a wrong letter.

Important! It is quite normal to listen to the correct word pronunciation by announcers as many times as you want.

The note: Try to recognize a word of a task while a singer is singing a whole line, using the Play Line button.

Word states in exercises Repair Word and Repair Obscure Word:

On-start state

The red underline designates any word with confused letters. It means that you have not begun this task yet, or you interrupted this task.

In-process state

The task is finished, but you have one or more errors.
no underliningFinished stateThe task is finished without errors.

Line states in the Repair Word exercises and the Repair Obscure Word exercises:

On-start state

You have not finished the task for all words of the line, i. e., at least, there is one word being in the On-start state.

In-process state

You have finished the task for all words of the line, but you have one or more mistakes. In this line, there are one or more words, which are in the In-process state.

Finished stateAll words of this line are in the Finished state.

Doing Exercises

You can enter an exercise and quit it, saving its current state automatically. However, entering the exercise does not mean the beginning of doing it. To start the exercise, you need to make active any task pressing the Space key or to double click with your mouse on any line or any word, depending on an exercise type.

If the current line is in the On-start state, you can activate the task object with the Space key. The indicator, as well as the pink frame designates the current line. In exercises dealing with words, the pink underline designates the current word.

You can change the task object using arrow keys:

UpDown — both keys relate to lines,


Left, Right — both keys relate to words in exercises dealing with words.

Another way to change the task object is to click with your mouse the wanted word or line (from the left of the wanted line).

If you have begun any exercise, the software indicates for you the nearest task objec,t which is in the On-Start state . You can begin the task pressing the Space key, or doing the double click.

After the implementation of any task, the next task appears automatically if the Next Task check box has been set as Auto. You can change the setting of this check box as shown below.

Counting Your Points

The software counts the sum of points while you are doing the chosen exercise.


The software considers this sum as your result. The result does not depend upon the time, which you have spent on doing the exercise. However, there is the time limit (60 minutes) for any exercise. The software resets the exercise into the On-Start state , if you have exceeded the time limit.

There are two resulting sums, which are considered as Good and Excellent. You can always see the Good result and the Excellent result on the Score pane of the Tutor. Authors of the software recommend you to do exercises till you begin to receive the Excellent results very often. The authors also recommend you to do all four exercises to memorize lyrics in your memory for sure.

There is the additional way of user result estimation. This is an average criterion. The calculation of the average sum is the foundation of the algorithm. The average criterion takes into consideration the amount of correct operations, errors, hints and time.

The note: The average criterion was developed for competitions between several participants and is not assigned for a single participant.

Resetting Task Objects

The software considers any exercise as finished if there is not a single line, which is in the On-start state. This is valid for all four types of exercises. After the exercise is finished, you have two opportunities:

— to start the exercise anew,


— to return to the finished exercise for the correction of errors.

If you want to do some task once again, before the current exercise is finished, you have two opportunities to do this. You can choose from the Exercise menu, or from the context menu

— the Reset this Line command (this command resets the current line, or the chosen line to the On-start state);

— the Reset All In-process Lines... command (this command resets all In-process lines of the current exercise to the On-start state).

After the processing of the chosen command, the software generates new task objects for chosen lines, and decreases your score (in accordance with values for task objects, which you have reset).

The note: You can reset only lines (not words) in all four types of exercises. The resetting of any single word is not  supported.
