Name That Tune

Figure from experiment 3 from Forensics with Vernier


On Tuesday night, wealthy recluse Tajia Winslow was robbed of her famous collection of rubies, known around the world as the Winslow Ten. The rubies were stored in a safe behind a painting in Ms. Winslow’s basement. The safe has a computer lock similar to a telephone keypad. Each time a number on the pad is pushed, a specific tone sounds. This method was developed to assist Ms. Winslow in opening the safe, because she is elderly and has difficulty reading the numbers on the keypad. She thought she was the only person who knew the tune of the combination.


  • Identify the musical notes that make up the combination to a safe.
  • Detect the waveform of a musical note, using a Microphone.
  • Calculate the frequency of a musical note from the period of its waveform.
