The footage to gather

  1. The instrument setup
  2. A short phrase slowly
  3. The phrase at a comfortable pace

Give each moment a little breathing room. Get close enough to show the detail, and keep the original clips handy.

Plan a revision-ready brief

Opening

List the available clips and the one non-negotiable moment.

Middle

Separate story instructions from style preferences and state what may be shortened.

Ending

Define one concrete criterion for approving the edit.

Review it for music teachers

Keep the example achievable and use music you have permission to publish.

Ask yourself: Does the brief explain how to judge a first cut?

Watch it as if you were seeing it for the first time. If something is unclear, try a different cut or add the missing shot.
