Ay the moment we are playing Holst "The Planets" with the RSPhO.
Can somebody who knows about physics explain to me why a bass oboe plays in the same register as a bassoon even though the bass oboe is only half the length of the bassoon. They are both instruments with a closed tube, doubble reed and a conical bore.
Beats me.

I have no certain knowledge about this but I suspect that the bore widths of the instruments are quite different. That is, the bass oboe's bore diameter opens up much more 'steeply' than the bass oboe, rendering its pitch of the same length of air column as the bassoon as lower.

but remember...the bass oboe does not play as low as the bassoon...the range of the bassoon goes an octave lower than what you can play on the bass oboe. It's lowest register lies in the middle register of the bassoon, so if you think about it in those terms, it makes a little more sense. (I think)

Josh... You're absolutely right. Thinking about it again, I was comparing the bass oboe to a bass clarinet that has the same register downwards as a bossoon, not thinking of the extentions downwards that both a bass clarinet and a bassoon have compared to the bass oboe. Brain failure after a tiring concert. Thank you.
