The one and only acoustic instrument?

piano - very hard to reproduce all the nuances

Joni Mitchell Down to You, Same Situation off Court & Spark
Laura Nyro - The Looms Desire Album
are two good examples

next cello - all those warm overtones

I play upright bass

This is a useful reference for what various instruments can do.

I have a framed print copy hanging in my listening room for reference.

Piano offers more data for making an informed, rational decision. Guitar resonates more personally for me. So, if my left brain is running this show....

that is the coolest chart
thanks for sharing!

it would be wonderful if you touch a spot and it give the tone for that instrument

That chart helps me understand why my 2-way speakers that cross over at ~ 7khz sound (blue zone on chart) so coherent and right compared to many that cross over in the yellow and green regions. That and them being omnis make for an effective combination of fundamental design advantages.
