The research aim was to develop a visual training simulator with real-time audio correction using the Python programing language and reference audio files classified library. Depending on the melody perception and playback level, the learning pace increases from the minimum. The desired result is affected by the repetitions number. The designed simulator having real-time visualization option allows estimating results and errors. The proposed methodology practical value can be effective for preschool educational institutions music teaching and other music schools and universities music subjects. Further research will be devoted to this technique improvement using virtual reality methods.
