Why would someone need to tune to A445 instead of A440??

Most tuners have a setting to produce a pitch or tune to A441, 442, etc. Keyboards can be tuned manually to match wind instruments, and in most cases tuning a wind instrument is not that difficult (10 years of trumpet experience).
However, setting the tuner to A445 clearly means that you want to tune a string or wind instrument to that pitch. Why would this ever happen? It can't be for out of tune pianos because the piano will probably be off by more than 5 Hz at A440, and you'd just tune to the piano.

Some folks just like the sound better. I've heard some folks say that they find the sharper tuning more "clear," although I've never really heard this myself. It just makes you stand out (and not in a good way) if everyone else is tuned to A-440.
In 1939, an international conference recommended that the A above middle C be tuned to 440 Hz. This standard was taken up by the International Organization for Standardization in 1955 ( reaffirmed in 1975) as ISO 16. Since then it has served as the audio frequency reference for the calibration of pianos, violins, and other musical instruments.
But an A has not always been 440 Hz. Take a look at Wikipedia http://en.wikipedia.org/wiki/Pitch_(music)#Historical_pitch_standards and you may be surprised to find that a Concert A has been documented at tones ranging from 380 Hz to 480Hz!

The standard tuning for orchestral instruments is with the note "A" equalling 440 beats per second. Sometimes, however, you may be playing with other musicians who have instruments which are either tuned sharp or flat. Rather than having them retune (which may be more difficult on a trumpet or clarinet, for example) you can tune your keyboard up or down to match their pitch, so that you are in tune with each other.

I'm a drummer but i can answer this. 440hz is the note A in western music, 440hz means the string vibrates 440 times per second. In eastern music though A is 444hz the difference is very hard to hear you really need to be a trained musician to hear the difference. The differnece between a flat note and regular note is very noticable and they can differ by 30hz!

Not all parts of the world use 440.
