buffet- sound nicer :) ------------------------------------------------------------------------------------------- I play noblet clarinet. My friend plays buffet. I suggest both because both of them have good quality sound. When I play noblet clarinet, playing the middle Bb and B(not the low) is very hard and the exact right tune won't come out. But the high and and low notes are awesome on noblet. On buffet the B and Bb are alot better then noblet. But the other notes aren't as good as noblet. I suggest noblet but buffet is great too!
The International is the C13, a very nice intermediate clarinet.
Buffet Crampon made their first clarinet in 1825 in France. They now make a variety of woodwind musical instruments and have manufacturing facilities around the world.
The list I consulted said 1908.
The Buffet R13 Bb Clarinet's are the world's most popular instrument made by Robber Carre in 1955 that has unparalleled flexibility and a lively, responsive sound that cannot be found anywhere else.
