Using the colored
switches at the top of the screen, you can turn the various instruments
of the orchestra on and off.
The best way
to start is to first switch off all instruments via the "All"
button (far right) and start the performance with the "Play"
Then click on
the two oboes ("Ob1" and "Ob2") and then
gradually add more and more instruments and observe how they each occupy
their own quasi-demarcated areas or "territories"
in the formant field.
the timbres are to each other in the formant field, the more similar
they should sound.
