Before you start
- Allow the microphone when your browser asks.
- Play one open string at a time. Rest a hand on the others so they stay quiet.
- If the reading jumps, stop the string and pluck it again.
- Go round all the strings twice. Tightening one string changes the others a little.
- If you play the tones while listening, use headphones, or the microphone will hear them.
Leave this as it is unless you have more than one microphone.
The numbers behind the reading, and what your microphone reports.
