Watchmen have a 2⁄3 chance of being generated with a tin whistle. Vault guards will also generate carrying cursed tin whistles, providing a source for the shrill whistling sound a player will hear while escaping them (see the section on messages below).
Applying a tin whistle of any beatitude can wake nearby monsters from sleep; if your pet is close enough to hear the noise, then for the next five turns it will try to approach you more closely. Additionally, using a cursed tin whistle in a vault will immediately summon a guard.
The range of a tin whistle is sqrt(xlvl*20), which in practice is half the range of a leather drum. This results in a radius of about 4 squares at XL 1, 16 squares at XL 14, and a maximum of 24 squares at XL 30.
The tin whistle is incredibly easy to identify. In addition to the above means of generation, you can apply any unidentified whistle; if you produce a strange or humming noise, then you have a magic whistle. See the messages below for further reference.
The best use of tin whistles is for attracting pets by applying one repeatedly until they come to you; this can sometimes help you take pets through stairs or out of shops. Once you find a magic whistle, you can safely stash the tin whistle elsewhere. Knights can also apply tin whistles to wake sleeping monsters before attacking them in order to avoid violating their code of conduct - for most other situations involving waking up monsters, other instruments such as a bugle are the superior choice.
The tin whistle has been present in the game since the first version of Hack. The effect of cursed tin whistles in vaults was introduced in NetHack 3.6.1; 3.6.2 gives the vault guards their own cursed whistles.
