Diff: WaterfallKeys

  

 Of the spinet organs, only the M-series had waterfall keys. Later spinets had to compete with other electronic organ manufacturers and most of them were using DivingBoardKeys. As with the consoles, only the M '3' series has radiused edges. 

  

 WaterfallKeys are preferred by non-classical organists because they're easier to play slides (glissandi) on. Unlike a thumb gliss, non-classical organists will often ''palm smear'' up and into a chord. This exposes the webbing between the thumb and forefinger to the sharp edges of other types of keys. As a special effect, they are also easier to jamb a matchbook in front to hold down a key while playing elsewhere...
