For the majority of instruments f = n f0 where f is the resonating frequency, n is any whole number and f0 is the fundamental. 
<span>This applies to trumpets, violins, flutes and a broad range. </span>
<span>In such a </span>case<span> the first harmonic would be at n=1 and the second harmonic would be at n=2 </span>
<span>which gives a frequency of 84 Hz</span>
