Guts.

Amen! The perfect short answer.


The long answer follows:

Embouchure and breath control produce tone. You can pucker up and blow or draw on a bare reedplate and produce a sound that is as good as (and arguably better) than a fully assembled harp because YOU are there. Given this, how important can all of the mechanical parts of the harp be to tone? The mouthpiece assembly (on a chromatic) and the comb are there to direct the air to the desired reed. The covers are there to keep your hands off of the reeds.

Plastic and metal combs are stable in the presence of moisture. Wood is not. Threaded fasteners (as opposed to nails) facilitate maintenance.

Reed design is a function of the density & elasticity of the material, and the desired response to breath pressure. Density and elasticity are virtually the same for all copper-alloy reed metals. Steel reeds would probably have a longer fatigue life than brass or bronze. Their thickness profile will be different but not necessarily their sound. The characteristic harmonica tone comes from the throttling of air by the changes of flow area as the reed swings back and forth in the slot. This is the same for any reed material. The sound does not eminate from the surface of the reed (or any other harmonica part) as from a bell or the soundboard of a stringed instrument.

Leakage (especially through the slide of a chromatic) interferes with your ability to establish tight, resonant connection of the reed to your embouchure. Without a long discussion of damping, you can think of it as the sound vibrations leaking out. It is like the sound of a brass instrument when you open the spit valve.

Bottom line:
Develop your embouchure and breath control for tone.
Choose your harp materials for longevity.
Choose your harp design for maintainability and low leakage.
Choose your price based on your pocketbook.

Then, don't worry about the many popular myths and superstitions (e.g. "wood sounds warm") about harmonicas.

Skeptically yours,

Vern

doesn't matter either.....

and apparently reed material doesn't matter (except perhaps for longevity).
so, what other factors are there. which ones matter? how much?
