Category talk:Musical keyboard layouts

Isomorphic Keyboards
Many of the layouts in this category are isomorphic layouts and should go in that subcategory. Specifically: and possible Robert Holford Macdowall Bosanquet, but the description of the keyboard is vague enough that I cannot say for sure. I am unsure if an item can belong to both the Musical keyboard layout category and the Isomorphic keyboard layout category. If that is the case, then there should be no problem simply marking all of these as isomorphic. However, if marking them as isomorphic requires that they be removed from the parent category, then I hesitate to remove so many items without consensus. Gravensilv (talk) 15:39, 27 May 2020 (UTC)
 * Chromatic button accordion
 * Free-bass system (Overwhelmingly, but there are a few obscure free-bass systems that are not isomorphic)
 * Jankó keyboard
 * Schrammel accordion (Which is the same system as Chromatic button accordion)
 * Wicki–Hayden note layout
