Inner Diameter	larger	low register easier to reach, better fit for larger embouchure	tendency to play flat, darker, with a fuzzy tone, and lack of endurance
Rim Thickness	thicker	more endurance, better for thin lips	less response and flexibility
Rim Thickness	thinner	better response, more definite placement, better for thick lips	less endurance
Rim Contour	flatter	more endurance, more stability	less response and flexibility
Rim Contour	rounder	better response, more definite placement	less endurance
Crown	higher	better response, more definite placement	less endurance
Crown	lower	more endurance	less response
Rim Bite	sharper	better response	less endurance
Rim Bite	rounder	more endurance	less response
Cup	shallower	high register easier to reach, better fit for smaller embouchures	thinner, brighter tone
	deeper	low register easier to reach, better fit for larger embouchures, bigger, darker sound	darker, fuzzy tone
	"C"	bigger, darker sound with more warmth	more resistance, larger volume of air to control
	"V"	brighter sound, more projection	less resistance, thinner sound
Throat	larger	less resistance, darker sound	high register harder to attain, fuzzy sound
Throat	smaller	brighter sound, more projection	more resistance, thinner sound
Bore	larger	less resistance, darker sound	high register harder to attain, fuzzy sound
Bore	smaller	more resistance, brighter sound	stuffy, thinner sound
Backbore	larger	less resistance, darker sound	high register harder to attain, fuzzy sound
Backbore	smaller	more resistance, brighter sound	stuffy, thinner sound
Mass	less	increased projection, response, comfort	thinner sound
