A typical French horn consists of about 3.7 m (roughly 12 ft) of thin tubing, rolled into a spiral shape. The player blows into the mouthpiece, which can be treated as a closed end, and places his hand in the opposite end, which has a large flared opening. In brass instruments, the fundamental note is not normally playable; instead, the first overtone is the lowest playable note. If the player’s hand keeps the large end open, what is the frequency of the lowest playable note?
