Third proposal/ M teacher

This next proposal is for music student or anyone trying to learn how to play an instrument.

The M teacher is a device that you place on a surface near you while you play and records the notes it hears, analyses them against the original of the song you where trying to play and then when u are finished points out where you strayed off course of the original and gives hints on how to improve.

In order for this to work the user would have to program the official songs they are trying learn so that it has something to go off.

This devise will have several different setting so that you could use it with many types of different instruments.
