Blue Whales Sing All Day When They Migrate and All Night When They Don't

[eppur_se_muova]

3. I used to have an LP that featured the voice of the blue whale.

With some nice homebrew speakers that had really good low-freq response, I could crank up the volume and make the counterweighted sashes in my apartment "walk" up and down. Amazing to think a living creature produced that sound.

(The music was "Blues Cathedral" from the "Callings" album by Paul Winter and the Winter Consort. It featured a recording of the blue whale at natural speed, double speed, and quadruple speed, which raised it two octaves into the audible range. Oh, and there were a couple of contrabass sarrusophones, for fans of such. Incredibly, when the album was re-released on CD, the natural speed version -- the one thing on the album which would have benefited most from the new technology -- was omitted !! I think most speakers just couldn't reproduce the low freqs, so they dropped it.)
