One-liner Guitar Tuner in Python

On windows, assuming imports are free:

import winsound
winsound.Beep(220*((2**(1/12.0))**7), 2000)

But that’s just because I like to tune to E. If you prefer a more “natural looking” note, you can use A:

winsound.Beep(110, 1000)

But why choose at all when you can go for all of them?

[winsound.Beep(220*((2**(1/12.0))**i), 500) for i in [7, 2, -2, -7, -12, -17]]
