A free-bass system is a system of bass buttons on an accordion, arranged to give the performer greater access to playing melodies on the left-hand manual of the instrument and to forming ones own chords, by providing a keyboard of single-note buttons, in contrast to the standard Stradella bass system. The term "free-bass system" refers to various left-hand manual systems that provide this functionalityDan Lindgren, " [http://home.swipnet.se/nydana/accordion.html#freebasscompared Free-bass Systems Compared] "] :

* Two related layouts exist as mirror versions of the chromatic button accordion.
* The "quint" or "convertor" free-bass system invented by Bill Palmer - later patented by Titano.
* Other less popular arrangements also exist.

History

By the year 1900, the Stradella bass system had principally reached its current construction with 120 buttons over 6 rows. However, while that setup worked well for major and minor music accompanied by many chords, the performer would only have access to about a single octave of notes while playing - two with a timely shift of registers. The problem was solved as early as 1910 by adding three rows of chromatically ordered single notes next to the standard bass [Bjarne Glenstrup, "Harmonikaens Historie" (1972), The University of Copenhagen (Faculty of Music), p. 43] .

Popularizing the free-bass accordion

The Hohner company decided to enlarge the market for accordions [Monichon wrote, "En 1912, la maison Hohner produira ses premières <> . . . . La 'Coopérative Stradella' mettra au point, en 1912, un instrument de 120 basses avec trois rangées de 'notes chromatique' . . ."—Pierre Monichon, Francesco Giannattasio and B. Bugiolacchi, Chronological Synthesis of the Evolution of the Accordion (1984).] by turning the instrument from its traditional music roots into an established instrument for orchestras [http://crosssound.com/CS00/CS00Instruments/CSTHEACCORDION/accordionENG.html The Accordion] , paragraph 25.] . An orchestra was put together, touring Germany to introduce the new concept. The company also supplied sheet music for this new type of accordion...] . Although these were reportedly popular, it wasn't until later the instrument became more widespread.

In North Europe, free-bass accordionist Mogens Ellegaard helped popularize the instrument and achieve compositions for it [Ole Schmidt made the following comment: "I hated accordion until I met Mogens Ellegaard. He made me decide to write an accordion concerto for him." Ole Schmidt, cited in the CD booklet for "Contemporary Danish Accordion Music", performed by Mogens Ellegaard with the Danish Radio Symphony Orchestra, conducted by Ole Schmidt (Solrod Strand, Denmark: Independent Music, 1987).] . In an interview he describes how the free-bass accordion was still practically non-existent in his childhood (born 1935), but how composers in his native Denmark began to write works for him since 1958. [Mogens Ellegaard, cited in "Interview," The Classical Accordion Society of Canada Newsletter (March 1990), 3-5.] . In 1968 he arranged the manufacture of accordions with nothing but free-bass layouts to accommodate newcomers, as free-bass accordions would otherwise always include standard bass.
