Reorganization of list   Ive just made a major edit and I wanted to take the time to explain it here in detail probably excessive detail now that Im reading it over What Ive done is to reorganize the list of instruments by transposition to make it easier to use for reference   I split the different types into article sections instead of a bulleted list so that someone looking for a specific transposition type can simply click on it from the table of contents  Ive organized everything at the top level by key with subsections for specific types eg high low This makes a lot more sense to me than going by size of transposition interval ie all high transpositions then all regular transpositionsIve kept this order for the subsections within each section  Ive added the qualifier regular to transposition types that didnt have one before Im not sure whether high very high and the like are useful but thats for another edit and another discussion  The D piccolo had been mistakenly listed under the header instruments in D Ive fixed this  Ive standardized instruments as being referred to as key instrument rather than as instrument in key eg F trumpet instead of trumpet in F  Ive added wikilinks to some instruments that previously lacked them  Ive also added a section of nontransposing instruments  I think these changes should greatly improve the lists utility
