According to the International Music Education Survey 2021, 79% of music teachers give online lessons, and this proportion is constantly growing. Technologies are developing, and even the once completely analog world of music teaching is moving online.

If classes in musical literature, music theory or sound engineering are easily transferred online using popular video messengers, then vocal and instrument teachers have faced serious limitations. Until now, the software has not kept up with the needs of teachers, and online learning activities have seemed inconvenient and even impossible.

Let's see what problems online music teachers face and what solutions can be found to solve these problems.

1. Sound quality. Indeed, this is important, and indeed current software solutions lose a lot in this. Often, due to noise suppression, sound can get in at all, high frequencies are muffled, and fine tuning is impossible. In addition, many students prefer to study through mobile devices, and their microphones are far from perfect, to put it mildly.
2. Feedback and desynchronization of audio and video. Everyone knows that during a call there is a slight delay between when the teacher speaks and when the student hears and vice versa, because the signal passes through the messenger servers. With the growth of Internet speed, this delay is getting smaller and smaller, but it is there. The desynchronization of audio and video streams, when the picture lags behind the sound or vice versa, also sometimes does not allow the teacher to understand whether the student hit the note or rhythmic pattern. Therefore, it is still quite difficult to conduct a student's performance, perform parts together and show accents.
3. No physical and direct visual contact. This is especially important for beginner students, when the position of the body, hands, and fingers has not yet been fixed correctly. In the first lessons, it is important for the student to be able to “mirror” the teacher and simply repeat after him. So far, popular programs do not allow you to work with the size of the video image, zooming, and other manipulations, such as mirroring the image. In addition, sometimes teachers working with children are faced with the problem of “inverted image”. The child does not always notice that he turned the phone or tablet upside down, and continues to play responsibly for the prescribed 3-5-10 minutes, when the teacher simply does not see anything. Sees more precisely, but not what you need.
4. Not possible to make notes. The most important moment, especially when working on homework. 10 out of 10 music teachers make notes in sheet music and tablature for the student for further development, but so far, for some reason, no one has proposed a technical solution to save these notes in electronic sheet music.
5. Need to change the camera angle. It is more difficult for a piano teacher to see the entire keyboard due to the size of the instrument (at least things are much easier with a guitar), and then the teacher has to ask to change the camera position in order to look at the right moment intently.
6. No option to connect external equipment. Many professional teachers are faced with the fact that existing video chats do not support the use of external audio cards, that is, it is simply impossible to connect and use a midi keyboard, electric guitar, professional microphone and any other sources of sound input and output in a lesson, but it is very necessary. After all, this is what brings online lessons to a whole new level.
