Vibrato: A rapid fluctuation of pitch slightly higher or lower than the main pitch.
Three Types for Violinists:
I have also included in this discussion a video of a guitar's visual string vibrations. This showcases the wavelengths and different frequencies of sound I spoke of in my first Theory Thursday blog. The high and low frequencies can be visually seen in this performance. The same thing happens on the violin and other stringed instruments. See if you can differentiate between higher frequencies (smaller and condensed wavelengths) and the lower frequencies (larger and broader wavelengths). Do any of you hear vibrato in any of the notes? Or see it?
