You can use a piano as an acoustic spectrum analyser to show that a hand clap has a frequency spectrum: open the lid of the piano and hold down the 'loud' pedal clap your hands loudly over the piano you will hear (and see) the strings vibrate to echo the clap sound the strings that vibrate show the frequencies the amount of vibration shows the amplitude Each string of the piano acts as a finely tuned resonator.
