==== Quarter-tone instruments ====

a very small number of quarter-tone pianos have been built which combine two keyboards (with the bottom one repeated at the top) in a single instrument. This arrangement works well enough for other keyboard instruments such as harpsichords and organs having multiple manuals to get different tonal quality and volume, but yields rather poor ergonomics for playing chords that span the keyboards~~; it~~ also makes instruments that either sacrifice power or are very large and heavy. Here are a couple of videos of these instruments being tested/played experimentally (to demonstrate their capabilities rather than to play specific compositions that would qualify for the 24edo Music section):
