Thsi is my Kravtsov Keyboard Accordion. Pictured with me are Vladimir Ushakov ( St. Petersburg musette ensemble ) and his good lady Svetlana. Both are terrific Accordionists and have an amazing knowledge of Accordion related info.Infact, Vladimir knows more about Accordion related info than anyone I have ever met!
This is the new ''Kravtzov'' keyboard.. It looks rather strange but it retains all the characteristics of a traditional piano accordion. This system gives the piano keyboard player, the same advantage that chromatic ( button) accordionists have i.e. 2 octave stretch, . It is easy to play chord passages ''legato'' . The shape of the keys allows you to play new types of glissando. You can have 10 sounds out of 12 instead of the usual 7 out of 12.
