When the pandemic hit we needed a quick solution for my daughter's piano lessons. I built a setup with OBS, Synthesia and an old Logitec web cam I had lying around (these were impossible to get new at the time).

I transmitted a frontal video of the player from the laptop cam, a top-down view of the center section of the keyboard (the cam angle was not wide enough for the whole), and the virtual keyboard from Synthesia. I had three different layouts of these elements in OBS, that could be switched by pressing the space bar. On the audio side I sent a mix from the laptop mic for voice plus the direct audio from the e-piano.

Served us well for the time.

One constraint that improved solutions probably don't have now was that teachers could not decide on a video conferencing software, so my setup-up needed to be independent. This almost made OBS a no-brainer, because of the virtual cam support.
