V Cup: As a cup approaches the “V” shape the sound becomes darker and the lower register becomes easier to play.
U Cup: The more “U” shaped a cup is, the brighter the sound and the easier it is to play in the high register.
Double Cup: A “double cup” design, essentially a combination of the “U” and “V” shapes, facilitates playing throughout the instrument’s range.
