Brass or Stainless Steel Reeds?

Stainless steel reeds vs. brass reeds
Both tones where produced with Bb harps (2-draw, F = 349Hz = 3.49 on the x-axes), at the same pressures and 40 cm distance from a condensor microphone with no cover plates in order to make it more comparable.

You can hear and see the difference!

Any tone consists of the fundamental frequency plus harmonious and disharmonious overtones.

There are much more overtones produced with stainless steel reeds (see range 1600-4000 Hz). This is one of the reasons for the fuller (or more bluesy) sound of stainless steel reeds!
