→Multiple keyboards in a single instrument: Ergonomics are partly dependent upon composition style

Related to the above, a very small number of quarter-tone ([[24edo]]) 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:

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. That said, some quarter-tone styles of composition mainly alternate between the two circles of fifths and only rarely play notes from both at the same time, and for such styles the ergonomic problem would be greatly mitigated.  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:


; Quarter-tone grand piano, Czech Museum of Music (this piano is essentially two stacked grand pianos, and as such is massive, in order to avoid sacrificing strings per note)
