Atzarin Posted August 31, 2010 Share Posted August 31, 2010 (edited) Here are some links to information about a new kind of bandoneon, called Atzarin Bandonion, which may be of interest to people who play Anglo concertina or a duet system concertina. https://www.youtube.com/channel/UCbeEmJNTR45DXESw5dT-sPQ?spfreload=10 http://atzarin.com/eng/instruments/bandonion/atzarin_bandonion_bandoneon_reshaped.htmlThe 3 row layout was originally intended for the treble keyboard of a bisonoric accordion, but it has since been developed on a new kind of bandoneon, specifically designed for this kind of layout. http://atzarin.com/eng/keyboards/bandonion/atzarin_bandonion_layout.html Although the best embodiment of this layout is the bandonion format described on the Atzarin web page, I feel that a smaller version could be applied to concertinas. It would be very intersesting to have people who play different types of concertina give their opinion on the layout, particularly bearing in mind the lengthy discussions in other threads on this forum about Duet systems and the possibility of a Wicki/Hayden bandoneon.The idea was to have a completely regular, fully chromatic instrument in both directions of the bellows, that would be neutral or isomorphic. So, the shape of a triad chord is one and the same in any musical key. The same is true of any minor triad chord. 1 scale pattern suffices to play that type of scale in 8 different musical keys, 4 on the draw and 4 on the push. A different scale pattern is needed in the opposite direction of the bellows. In total you only need 3 different scale patterns to play in any key in either direction of the bellows.Transposing is much easier as a tune can be played in a different key with exactly the same fingering and bellows reversals just by starting from a different button in the same row. Musical keys fall into 3 groups of 4, depending on which row the tonic note is on. Transposing to a key from another group is made easier by the fact that very often, motiffs and entire phrase can have the same fingering, but played in the opposite direction of the bellows.Another important consideration was that the fingering style should be comfortable and not completely alien to people coming from conventional diatonic or bisonoric accordions or even Anglo concertinas. Although different, playing technique may feel more familiar to people who play on diatonic accordions with rows separated by quarts than to people who play Irish B/C etc.Although the Atzarin layout requires learning a completely new system, transition is fairly quick and easy. Learning is very rewarding because the layout is 100% regular, so there is less memorisation of chord shapes, scale patterns etc.What should be the definitive bandoneon prototype is currently being built by bandoneon and concertina manufacturer Harry Geuns. The bandoneon model will have traditional style long, zinc reedplates and two voice (MH) bandoneon octave tuning. However, if there is enough genuine interest a dry tremolo tuned (MM) model can be built. Edited June 13, 2016 by Atzarin Quote Link to comment Share on other sites More sharing options...
