- | =====Things | + | =====What Exactly is a Reed? |
+ | There is a lot of contention (that I created no doubt) on making a clear definition of a reed. Past definitions are far too ambiguous in my opinion and a rehashing of the definition and classification of reeds in is order. in [[classification|' | ||
+ | |||
+ | =====The Previous Definitions of what a Reed is===== | ||
+ | Summarized from Wikipedia and Encyclopedia Britannica- \\ | ||
+ | reed "A thin strip of material that vibrates to produce a sound on a musical instrument" | ||
+ | |||
+ | This definition has a major issue in that is describes single reeds (lamell reeds like those of a clarinet or saxophone) | ||
+ | |||
+ | =====My New Definition of what a Reed is===== | ||
+ | |||
+ | A reed is any solid material that vibrates in a stable and consistent manner in response to wind as the generating force of the oscillation. | ||
+ | |||
+ | =====Understanding the Distinction Between the Two===== | ||
+ | |||
+ | For Reeds the following forces happen- \\ | ||
+ | Wind --> Material that vibrates in response --> Sound is reinforced (or regulated) and directed by a resonating tube (air column with standing waves) \\ | ||
+ | \\ | ||
+ | For flutes the process works as such-\\ | ||
+ | Wind --> An edge that causes an oscillation --> Sound is generated in the Air Column with Standing Waves or in a Helmholtz Resonator with Cavity Resonance ((http:// | ||
+ | \\ | ||
+ | With flutes and corrugation no material needs to vibrate in response to the agitation of the generation force, its the air itself that oscillates, not the solid material. \\ | ||

Membranophone- A double chamber where air passes from the outer chamber into the inner chamber which is typically a tube by forcing open a membrane that is under tension, membrane beats against the tube, requires some kind of pitch reinforcement to work at all. Works with both cylinders as well as cones (though not well with wide cones). I consider this definitely a reed, it is similar to how a double reed uses a surface with 3 sides mounted, but this version has all sides mounted. Perhaps it is comparable to a single reed version of a double reed in that sense. These are also capable of being made with rigid materials, though the pressure required is quite high. I am using the term membrane the same as how i use it on resonator chambers on string instruments. | Membranophone- A double chamber where air passes from the outer chamber into the inner chamber which is typically a tube by forcing open a membrane that is under tension, membrane beats against the tube, requires some kind of pitch reinforcement to work at all.

- | This definition has a major issue in that is describes single reeds (lamell reeds like those of a clarinet or saxophone) as well as free reeds (like those of a harmonica) but inadequacy describes the behavior of double reeds (or any other class listed above) because the focus is on the shape of the material. | ||

I find it to be a source of some frustration that it seems there is no one (that I can find) critically asking what a reed is. It seems like an excellent question in terms of how we discuss instruments, | I find it to be a source of some frustration that it seems there is no one (that I can find) critically asking what a reed is.

Another distinction is that reeds need to be rigid, and that warpable and stretchable materials dont count. This is similar to the ideas of membranes vs soundboards on string instruments. I take the same solution considering both the same thing (in the case of strings, both are membranes, one rigid and the other warpable). these distinctions are just describing materials that are or near opposite sides of a spectrum. I think the only distinction is to define them by the opposites, or by the difference of the material behavior (with options in the middle being allowed to be intermediate and there being no hard cutoff). with that said there is no way to form a clear delineation between materials that easily bend and warp and ones that resist the action other than that they tend to have different timbre, and the more bendable they are the less upper harmonics they allow (a kind of self damping harmonic filter?) (then again that also happens when lips dampen the rigid material anyways) | Another distinction is that reeds need to be rigid, and that warpable and stretchable materials dont count.
