This walkthrough shows MIDI input from both participants. The coloured keyboard represents note data; it is not a measurement of microphone volume.
Written walkthrough
Connect a MIDI-capable keyboard to the computer with a suitable data connection. Open the classroom in a browser that supports Web MIDI and allow the requested access. Check local input first, then ask the other participant to play. Take turns so each signal is easy to identify.
Recording script
Show the connection. “The instrument sends note information through the cable. A charge-only cable will not carry that data.”
Local keyboard display. “My notes appear in lime on my screen. I play a soft note and a firmer note to compare the velocity indication.”
Peer response. “The other participant’s notes appear in orange on my screen. On their screen, their own notes are local.”
Take turns with C–D–E. “We can compare the notes and the attack. We still listen to the musical phrase.”
Capture notes
Use two demo participants and label the local perspective. Do not imply the colours permanently identify teacher and student. Check browser support before filming.
