Go to your mic settings and switch to Standard or Wide Spectrum so your guitar comes through clearly.
‣
Camera: Show your face AND your hands
Angle your camera so I can see both. This is how I diagnose technique issues.
‣
Stability: Don't hold your phone
Prop it up sideways so that you’re not blocking the microphone or use a stand. A shaky camera or bad audio makes the lesson harder for everyone.
‣
Background noise: Quiet room if possible
Close doors, turn off fans or TVs. The cleaner your audio, the better the feedback.
‣
Come prepared: Have one clear goal
Know what you want help with before you join. "I want to understand how to transition between these two chords" beats "I don't know, whatever." You'll get a much better lesson.
