Does anyone with what scientific instrument you would be able to measure and record the overtones from different combinations of notes? (btw, a piano will be used in this study, if that's of any further help)

a meter and one or more notch filters would allow you measure the energy of each overtone (as well as the fundamental)
An oscilloscope would be useful in visualizing as well as measuring peak to peak components.
In addition to the overtones, you will produce BEAT FREQUENCIES when you play more than one note (except an octave) on a piano. This is because a piano is tuned to the EVEN TEMPERED SCALE, so the notes are not perfectly related harmonically. To see this, it might be more useful to trigger the scope on the fundamental of the lowest note, and subtract the fundamentals and direct overtones from each note from the display using notch filters as above.

An oscilloscope that gets its input from a microphone will show the harmonics (overtones). You can use the oscilloscope controls to filter out frequencies to examine each standing wave harmonic individually.

I would think some type of oscilloscope . . .
Or a type of computer software . . .
Here's a configuration:
