Open the MatchMySound exercise that the teacher has assigned to you or what you have chosen from the content list. The green play button starts the playback and you will hear the demo audio track and see a moving cursor. It is synchronized with the sound so you can see how the written and played music align at any given moment.

Your main goal is to repeat the demo performance on your own instrument. To do so, please press the red record button. You will be prompted by a request to share your device’s microphone. It is necessary that you grant the rights for the application to be able to hear your playing. This is a one-time action and your choice will be remembered. Some exercises come with a play-along backing track. The backing track can be enabled from the icon next to the ‘Record’ icon and it will play once the recording has started.

Note: Recording with a backing track requires earphones to get unbiased scores. Recording with metronome can be done with or without earphones. The score will not be affected.

The recording starts with two bars of count-in clicks from the built-in metronome. Start playing and you will see the moving cursor loosely following you. When you reach the end of a line, the page will be automatically scrolled down so you do not have to take hands off your instrument (see automatic page scroll).

Once you reach the end of the piece, the recording stops and your input will be analyzed. After a few seconds you will see the initial feedback window showing the numerical scores of your playing. Close it and you can see the colored graphic feedback in two modes: basic or full. The detailed numeric scores can be re-opened by touching the scores area in the right upper corner.

You can now listen to your recording (see the play button) and toggle between the original track and your playing by placing the cursor to either the notation line or the colored feedback line.

How to read the feedback

Green indicates that your playing sounded close to the original (see etalon) whereas red shows the spots where there was a substantial difference. Yellow lies between thos two and may mean that you did something correctly but there is still room for improvement. You will learn to interpret the graph over time and will find that the full view even shows you the changes in your articulation. The curve moving up and down shows that you have either rushed or been too slow compared to the original. You may want to record a second or even a third take.

If you are happy with your scores and/or have reached the set score goal, you can either move on (if you are a self-learner), or submit your performance to your teacher by Submit button.

Your teacher will review your performance and can comment on it. You can comment as well. (see commenting submissions)

The algorithm works well for most exercises and most instruments. There are, however, some known algorithm shortcomings.
