English: I drew a musical instrument classification chart in GIMP, and then ported it to Inkscape, and then I got a professional graphic artist to help with making the layout look nicer, but unfortunately the graphic artist uses commercial software on a microsoft computer, so I had to redraw it to be compatible with uploading to Wikimedia Commons as an SVG file.

The file is also in http://wearcam.org/symphone.svg e.g. in case there are issues or problems in the upload changing it.

Here's a link to a high-resolution version of one of the images, often cited and used on its own, contained in it: http://wearcam.org/dusting/eeg_electrodes/regen_poster_colour.jpg

NOTE: I am using the subtitles "Earth", "Water", "Air", "Fire", and "Idea" metaphorically, in the poetic sense of Ancient Greek texts, and these should not be considered accurate representations of their corresponding state of matter. This chart connects the five classical elements (from Aristotle) to states of matter, proper only in such instrumental organology and not intended to be physically accurate. In the traditional ancient Greek sense, "Earth" represents solid matter generally, not just dirt or soil (which may contain air or moisture), and "Water" liquids in general. It should be clarified that fire is not the same thing as plasma, but involves plasma (e.g. the flame-rectifier, flame sensor in a hot water heater, etc.), as fire is a chemical reaction, whereas plasma is a special gas state that contains interacting ions (charged particles) as opposed to non-interacting particles. Unlike what the image suggests, plasma is not merely an electrically charged gas, nor a "fire", but is used loosely as a poetic metaphor for this fourth state of matter.

Furthermore, "Quintessence" appears in quotes as it is used again, as a poetic metaphor in the sense of ancient writings, as a "process" not as a denotation of the vacuum energy responsible for the expansion of the universe (dark energy). As with computer software which cannot exist without a physical computer, we use the term similarly, even though algorithms, or other processes are physical and are limited to space. Here I am using the term Quintephone to broaden the concept of electronic instruments, i.e. electrophones, as a proper subset of quintephones, and the category quintephone is necessary to describe computational sound synthesizers that operate by other-than-electrical means, such as synthesizers that work using optical computing. They generate their sound informatically with no intended relation to physic's Quintessence, instead referring to the common meaning of the word as the pure form of something.

The spelling is corrected in a further uploaded version of the image.
