Re: [tuning] Digest Number 2103

THat's because a column of air vibrating in a long pipe will greater lengths
between the 'nodes'. and so, like strings, you need to alter by quite large
amounts (tape, finger movement), for the nodes to shift (change in boundary
conditions) by a small amount.

Think about it:

moving a finger up by 81/80 for a 30cm violin string is a _lot_ smaller than
for 120cm of bass string. (apologies in advance for incorrect string
lengths, but you get the idea...
