Final answer:
Use a center punch to accurately locate and begin drilling holes in a pipe, after which you calculate the required length for resonance, mark the locations for holes, and use tuning forks for calibration before demonstrating the instrument.
Step-by-step explanation:
To accurately locate and begin drilling a hole on a pipe for creating an instrument, you should use a center punch. Prior to this, you need to calculate the length required for the pipe to resonate at a certain frequency and then mark the locations where holes are to be placed to achieve the desired pitches.
After drilling the holes with a simple hand drill, you can use tuning forks to test and calibrate your instrument to ensure it produces the correct tones. It's important to demonstrate the finished pipe instrument to the class for a complete understanding of the project's results.
