1. Prepare materials: Select a piece of Tai Chi music and convert it to digital music format for editing on the computer.

2. Editing processing: Use audio editing software to edit and splice Tai Chi music to create an extended version. You can edit it into different parts as needed and then splice them together.

3. Synthetic sound effects: After the editing is completed, add some sound effects to enhance the effect of the music. You can add some sounds of running water, birdsong, etc.

4. Adjust the rhythm: Since the rhythm of Tai Chi movements is slow, the rhythm of the music needs to be adjusted to a speed that matches the Tai Chi movements.
