Tyros 4 Chromatic "B-griff" keyboard
« on: January 02, 2018, 07:33:46 AM »
Have come across this YouTube video of a Tyros 4 with a Chromatic "B-griff" keyboard.

I Can't Stop Loving You

Recorded live with only the “Yamaha Tyros 4” keyboard possibilities by Paul Huybrechts - no midifile or backing tracks.
Yamaha Tyros 4 equipped with chromatic “B-griff” keyboards.




I am completely spellbound!  What an amazing video!  Until this point I had never heard of a chromatic "B-griff" keyboard ! ?  Has anybody else heard of one of these?  When I first saw it I thought it would be 'played' like a 'button accordion'.  But notice that when he pushes the buttons down other 'buttons' go down with it.  So what exactly are his 'buttons' connecting with in the Tyros 4?

I had come to the conclusion that the set-up of buttons must be from the Chromatic Piano Accordion, but as I have never played one (only a Piano Accordion) I had no idea how the notes were made up.  I have come across this YouTube video explaining how the "B-griff" keyboard buttons are made up from the notes on a piano.



The whole idea of having the buttons in this arrangement is so that you can get all the black and white piano notes to fit into about half the space required for a piano.  Although I have noticed that the Tyros 4 "B-griff" doesn't have any 'black' buttons, so all sharps and flats look the same as the 'white' notes.

This has answered one question for me.  The top two rows of buttons are the same as the bottom two rows of buttons, so that is why those other white buttons go down at the same time as the ones he is pressing.  And the reason for this is is to make the 'fingering' easier as you can press a higher button or a lower button to make the note sound.

Here are some more videos showing the chromatic "B-griff" keyboard being played.











I suppose that Yamaha must make the Tyros 4 with a "B-griff" keyboard as well as the "Piano" keyboard?  Maybe for the German and Swiss market?
