Instrument frequency 2 - another useful wee chart with fundamental frequencies of quite a lot of instruments.

As an aside, if you know the range of the instrument you can work out your own chart as the fundamental frequencies will be the same - a 440 A is a 440 A regardless of instrument. Most of the charts only cover the fundamental range of the instruments rather than what part of the overtones make a huge difference to the sound. I presume that is something down to the shape of the wave / nature of the instrument that determines it and that is way beyond my limited knowledge.

The other thing I have heard mentioned is to chop everything under (I think) 40Hz with a high pass filter.
