A spectrogram is a picture of sound. A spectrogram shows the frequencies that make up the sound, from low to high, and how they change over time, from left to right. With this experiment you can compare spectrograms of different sounds, or use the mic to see what your own sounds look like.
A basic chord is made up of three notes. Tap a note on the piano to play a chord starting on that note.
