  Audio Transcript

  The squelching sounds of a person playing a harmonica.

Spectrogram of a harmonica. Spectrograms are graphs that visualize sounds. The brightness of the colors shows sounds’ amplitude (loudness) across different frequencies (pitches), shown from bottom to top, and over time, from left to right.  This spectrogram visualizes the changing frequencies and harmonics as the musician changes notes.
