Summary:

• Objects of different materials and shapes vibrate at their own set of natural frequencies.
• A spectral analyzer measures the different frequencies present in a wave spectrum.
• Musical instruments have a spectra “signature” called the timbre, also known as tone color.
• Ocean waves and other natural wave phenomena also have spectral signatures.
• Spectral signature varies with material properties and with scale.
