These are the best images we’ve found yet of the early chalumeau: descendant of the recorder and predecessor of the clarinet. Notice the unusual position of the reed: played against the upper lip, rather than the bottom lip as today. On the left is a chalumeau in C (by Liebav) and on the right, one in F (by Klenig) from the early 18th century. (Musikmuseet, Stockholm).
