Version 0.7

Change in the definition of a musical instrument
Old- Any sound generating device that is used for the purpose of making music.
New- Any sound generating device that can be used for the purpose of making music.

Version 0.6

Clarification on meanings

Lamell-Membrane, 3 walled Lamell, True Reeds, Sheltered Reeds. The exact terminology is unclear
Reed- Any air blown material that can be mounted into a tube that has pitch reinforcement.
Invert reeds are now Labrophones. Clarification that there can be both rigid and elastic labrophones (perhaps rigid are called invert reeds specifically).

Clarification about the importance of examples that have both turbulence and consonance, consonant instruments minimize the amount of effect that unique combinations of the generating force and material objects have one one another, the differences between similar classes are much more pronounced on instruments with greater degrees of turbulence in their function. Think of the screams I developed using a lamell-reed versus attempting the same function with a true reed. The true reed has far less ability to have an unstable vibrational pattern because the walls are reinforced (or sheltered) and even lass is able to be done with a crushed reed because the damping reduces upper harmonics. (in this sense both have a form of damping, one harmonically dominate and the other pitch stabilizing but effecting harmonics less).

this is a unique point that is mostly undiscussed because most instruments are attempting to maximize how consonant they are and therefor rarely encounter timbre that is most directly related to the mechanical function of the reed. Another way of saying this is that the more chaotically a reed vibrates the more able it is to demonstrate unique functions of its mechanics and the easier it is to distinguise by its sound alone from other kinds of reeds. Orchestral instruments minimize the limits of how much their reeds do this in multiple ways, via the construction of the reed, careful standardization of sizes and use, and the careful use of pitch reinforcement in the instruments bore (for example not placing a contrabass sax reed on a soprano sax or vise versa) Everything is carefully regulated to function with the other parts, therefor limiting instances of chaos.

New classifications

Pitch reinforcement- when a tube or resonator is attached to a sound generator that causes a specific pitch set to be generated in response to the internal resonate frequency of the tube. An example would be the tube attached to a reed that makes up a woodwind instrument.

Pitch regulation- when the pitch generator in a reinforced system responds to the system in such a way to regulate and maintain an vibrating equilibrium. Typical examples would be the ways that the lips manipulate a reed in a woodwind instrument to adjust timbre, volume, articulation and pitch. The lips are not required for a woodwind to generate a tone but are required for the regulation of the tone.
Pitch regulation is now a modulation class


Lamella is now just lamell, the ending a is unnecessary unless used as a conjugation such as lamellophone

Version 0.5 and older

This is the version I applied with in December of 2022, the prior versions are all blurred together because of the rapid development of the ideas.
