rlgph Posted June 16, 2015 Share Posted June 16, 2015 The thread about small concertinas has gotten me thinking -- often a dangerous thing -- about the possibility of an instrument that has the ease of changing keys characteristic of the Wicki/Hayden layout, with the compactness inherent in the Anglo/bisonoric approach to key layout. The proposal described below is meant to apply to the right side only, where typically the melody is played on a duet. The idea is sufficiently simple that it has probably already been thought of by other people (who may have also found potentially fatal flaws), but at the risk of showing my ignorance yet again, here it is: Suppose we apply a bisonoric key arrangement such that changing from a push to a pull is equivalent to shifting upward one row on the Hayden layout. So, for example, the first four rows of a standard unisonoric Hayden layout could be condensed to the following two-row bisonoric layout (notes left of the slash sound on a pull; those right of the slash sound on a push): f/c g/d a/e b/f# c#/g# F/C G/D A/E B/F# C#/G# This layoout retains the highly desireable property of the Hayden layout in that just shifting the hand one or more set of buttons to the right changes the key, but retains the same fingering and bellows work for a given melody. So far as i know, the same trick could not be used on the left side, because (e.g.) one may need to play a low C accompaniment during either a push or pull melody note. The number of left side buttons could be reduced if one were willing to sacrifice the rows that overlap with notes on the right side for the sake of compactness. Or perhaps you have other suggestions for reducing the number of left side buttons Quote Link to comment Share on other sites More sharing options...
