Accordion - Construction

Construction

Accordions are made in a large number of different configurations and types. What may be technically possible to do with one accordion could be impossible with another:

  • Some accordions are bisonoric, meaning they produce different pitches depending on the direction of bellows movement
  • Others are unisonoric and produce the same pitch regardless of the direction of bellows movement
  • Some accordions use a chromatic buttonboard for the right-hand manual
  • Others use a diatonic buttonboard for the right-hand manual
  • Yet others use a piano-style musical keyboard for the right-hand manual
  • Some accordions are capable of playing in registers different from others
  • Additionally, different accordion craftsmen and technicians may tune the same registers in a slightly different manner, essentially "personalizing" the end result, such as an organ technician might voice a particular instrument

Famous quotes containing the word construction:

    There is, I think, no point in the philosophy of progressive education which is sounder than its emphasis upon the importance of the participation of the learner in the formation of the purposes which direct his activities in the learning process, just as there is no defect in traditional education greater than its failure to secure the active cooperation of the pupil in construction of the purposes involved in his studying.
    John Dewey (1859–1952)

    The construction of life is at present in the power of facts far more than convictions.
    Walter Benjamin (1892–1940)

    No real “vital” character in fiction is altogether a conscious construction of the author. On the contrary, it may be a sort of parasitic growth upon the author’s personality, developing by internal necessity as much as by external addition.
    —T.S. (Thomas Stearns)
