The accordion has undergone an amazing evolution in the last 20 years. Inspired by the design of the Russian bayan, several manufacturers have created beautiful-sounding instruments that are expertly crafted, with extremely reliable and quiet mechanisms, surpassing most accordions previously made.  The Russian influence has also contributed to standardization of the instrument.  There is a large body of original Russian accordion literature, ranging from virtuoso arrangements of folk songs to avant-garde pieces, many of which are now staples of the literature.  Since so many accordionists want to play these great pieces, interest in the instrument for which they were conceived has grown.

The design of the left hand manual uses the converting Stradella system.  The chord rows convert to a 58-note, 4-row chromatic system (free bass or melody bass) and the standard bass rows remain for use as pedal tones or to facilitate large jumps.  The right hand manual has a 64-note range with 15 possible registers.   There are two prevalent systems, C System and B System.  Further, the keyboard has moved toward the front of the instrument to provide a more natural arm position.  Chin registers are now ubiquitous.

Modified bayans 

A few bayans have been made which provide a more ergonomic fit for the player.  In one design, the right hand keyboard is more steeply angled to allow the player’s arm to remain straighter.  In the left hand, the first two rows of buttons are terraced to allow full facility for the thumb, thus facilitating arpeggios and many other technical concerns in left hand technique.

The Ergon Concept

The Ergon Concept simply continues this avenue of design.  The right-hand keyboard is further moved out from the player and more steeply angled to allow the arm to remain straight.  This way, the player doesn’t have to hold the elbow up continually while playing.  The left hand buttons are also angled more steeply so that the left hand doesn’t have to reach around the instrument to play, and so the hand can remain straighter.  Both of these modifications are achieved while basically retaining the existing, perfected mechanism design and reed block layout.

Views of Ergon Concept accordion.  The shoulder straps are not shown in any of the images.  The instrument is held and played just like an ordinary accordion, with the left arm pulling the bellows.  The right hand technique is unchanged and the thumb is used as before.  The left hand technique is the same except that we now have the ability to use the thumb in the first three rows of buttons.  Anyone who currently plays a bayan should be able to play it more or less immediately.

How does the Ergon Concept work?

The manufacturers have solved countless mechanical problems and have perfected a mechanism that is unbelievably precise, quiet and reliable.  The Ergon Concept retains this tremendous asset by simply turning the keyboards out and otherwise preserving the internal construction.  One way to achieve this is illustrated below. There are certainly other possible solutions.

This illustration depicts the Ergon Concept from the top in cutaway view.   The left hand buttons are visible with the first two rows terraced to allow the thumb full facility on the first three rows of buttons.  The traditional piston rod mechanism has been turned 90° so that the keys now advance into the bellows rather than toward the player.  The reed plate on which the valves rest has also been turned 90° to stay parallel to the piston rods.  This has the twin benefits of straightening out the player’s left wrist and allowing the reeds to speak directly out toward the front of the instrument.  There may be some issues regarding retaining desirable weight distribution and sound channeling that would have to be worked out.


The right hand keyboard has also been turned out to allow the wrist to remain straight. The internal action has been only slightly reconfigured to retain the simplicity and reliability of the traditional mechanism. The tone chamber is now in the front rather than at the back. There are probably other solutions to this problem as well.

This page shows the logical progression from the current bayan to existing modified bayans and then to the Ergon Concept accordion.  Front, left, right and top views are presented in succession for each design.

Why change the bayan?

 

Today's bayan is a mature, fully-developed instrument on which all the literature can be played.   Thus, there is no compelling reason to modify it at all.  The Ergon Concept is not intended to be a replacement for the current bayan/accordion.  The Ergon Concept is simply an alternative construction that may appeal to some players.  My interest lies in pursuing the idea and making it available to those who can benefit from it.

Building a better accordion case

A report on my efforts to obtain a case worthy of my bayan.  You can check your accordion through at the airport with this case and feel good about it.
