What the Classical "C" chamber gives you:
The Morgan Classical has a round chamber needed for that rich classical sound, smooth even scale, precision control and singing quality that you are searching for.
What the Medium "M" chamber gives you:
Medium has a squeezed throat, a smoothly rolled-over baffle area and a long curved roof which produces that "POP" that you want without the sharpness in the palm keys. Perfectly even response, from low Bb to .....how high do you want? A compact, brilliant sound with maximum control and flexibility.
What the Large "L" chamber gives you:
Large has a larger, rounder throat area which produces the warm soaring sounds of the "BIG BAND" era. It has a long roll-over baffle and "live" brilliance with fine projection power. It gives the perfect control and subtone that you need.
