Sound Sample
The vibrandoneon is another development from Victoria Accordions (

It was found in Italy a few years ago by Guido Tononi and has original buttons, arranged like piano keys.
In principle it works like a melodica, but it is made of high quality walnut wood and has mouth organ reeds.
The instrument receives its air supply through a long curved mouthpiece.
The lungs replace the accordion bellow as it were, so that the instrument sounds somewhat more melancholic and human than the accordion, which is sometimes hard to tame.
