What is gondola instrument?

The gondola instrument, also known as the gondolier's whistle or the squawk box, is a unique instrument used by Venetian gondoliers to signal their presence and communicate with other boats on the canals. It is made up of a pipe or bamboo tube with a small metal reed at the end that produces a loud and distinctive squawking sound when blown. The gondolier can control the pitch and tone of the sound by altering the way they blow into the instrument, allowing for a range of different notes and melodies. The use of the gondola instrument is an important tradition in Venice and is a key part of the city's cultural heritage.
